Back home, I thought a fun exercise would be to try and dupe every single shade in the Sweet Peach palette with existing eyeshadows I have. If, in doing so, I could see I basically already had the palette, then any remnant need might be extinguished. I referenced swatches and descriptions online, namely here and here, to form the basis of the "dupes" I found.
Time to go digging...

This first row was meant to approximate White Peach, Nectar, Peaches 'n Cream, Just Peachy, Candied Peach and Caramelized.
I used Urban Decay Strange (from Naked3) for White Peach, the fifth shade in L'Oréal Color Riche La Palette Nude in Beige for Nectar, Anastasia Beverly Hills Soft Peach (from the Shadow Couture World Traveler Palette) for Peaches 'n Cream, NARS Orgasm blush for Just Peachy, theBalm FratBoy blush for Candied Peach, and Addiction by Ayako Fudge for Caramelized.
Compared with swatches online, I think the shades that were meant to dupe Nectar and Caramelized look the most off. Nectar in swatches looks slightly duochromey with an orange overlay over a lighter gold. I didn't have anything exactly like that in a single eyeshadow (I could potentially have approximated it layering two shadows on top of each other), though at least the fifth shade in L'Oréal Color Riche La Palette Nude in Beige had a similar shimmering quality. Caramelized looks like a colour I'd have at least 15 dupes of, but I tend to lump these bronze shades together since their differences aren't pronounced enough for me to meaningfully tell them apart. Having said that, Addiction Fudge seems way too warm (kind of bordering on an orange-brown poo colour) to dupe Caramelized, which looks darker and more chocolatey.
I didn't have any pink eyeshadows like Just Peachy or Candied Peach, so I had to resort to blushes. I've never used blush as eyeshadow and I'm not entirely sure why. I guess lack of adventurousness and a certain wariness of wearing pink around the eyes, which blushes tend to be. However I do remember trying the dominantly pink/peach Sleek Oh So Special and being pleasantly surprised at the results. Maybe it's time to get away from the mentality that pink is a strictly "creative", out of the box colour and start reaching for it like I would any other bronze or taupe.

The second row was meant to approximate Luscious, Cobbler, Georgia, Bless Her Heart, Bellini and Puree.
I used Makeup Geek Grandstand for Luscious, Morphe Burlesque (ES74) from the Jaclyn Hill Favorites Palette for Cobbler, Rimmel Santa Rose blush for Georgia, Witchy by Anastasia Beverly Hills (from the Self-Made Palette) for Bless Her Heart, Organza from the Sleek i-Divine eyeshadow palette in Oh So Special for Bellini, and Makeup Geek Cocoa Bear for Puree.
Grandstand is probably a bit too dark to be an accurate dupe for Luscious, which looks lighter, more overall silvery and reflective, with some muted brown in the mix. But overall, I'm hoping it captures the same metallic rose gold character. I totally guessed Morphe Burlesque for Cobbler since it's the same story as Caramelized in the first swatch — too much of a generic bronze for me to care about the minute differences between the shades I have that are similar. Georgia was one shade that I really didn't have anything close to. It wasn't in any eyeshadow palette I had and it's not the kind of colour I'd set out to buy on its own as I can't see myself getting much use out of it, as pretty as it is. Once again, I had to resort to a blush to approximate it (Rimmel Santa Rose in this case). Bellini was also tricky to find a dupe for — I initially thought Sleek Organza would be spot on, but it turned out to be way too shimmery and light. Needed to go for a darker peachy-pink. Makeup Geek Cocoa Bear isn't exactly like Puree, but I surprisingly struggled to find a dark, warm-toned brown with a strictly orange undertone rather than red. The one shade I'm convinced I nailed is Bless Her Heart, which ABH Witchy looks identical to.

Finally we have the shades that were meant to be dupes for Tempting, Peach Pit, Summer Yum, Charmed, I'm Sure, Delectable and Talk Derby to Me.
I matched them to Envy from the Sleek Bad Girl palette (second shade, bottom row), Australis AC/ME Eyeshadow in Plum Diddy, Too Faced Peanut Butter (from the Semi-Sweet Chocolate Bar Palette), the second last shade in L'Oréal Color Riche La Palette Nude in Beige, Morphe Midnight Kiss (ES48) from the Jaclyn Hill Favorites Palette and Anastasia Beverly Hills Spirit Rock from the Self-Made Palette.
The only one I think is obviously off is Summer Yum. I simply don't have anything that dark and orange. I even tried swatching matte bronzers and none were near the required intensity or warmth. Come to think of it, Makeup Geek Cocoa Bear is probably a better dupe for Summer Yum than Puree. The rest might not be perfect dupes, but for me, are close enough that I don't feel I'm missing out. Australis Plum Diddy (for Peach Pit) is a cream shadow, which doesn't have the same functionality/versatility as a powder one, but I'm sure I have similar eggplant/dark purply brown shades tucked away somewhere.
Overall, the only shades I felt I really didn't have sufficient approximations for were Nectar, Georgia, Bellini, Puree and Summer Yum. Of those, it's only the mattes (Georgia, Puree and Summer Yum) that I'd consider worthy additions if I did buy the Sweet Peach palette. When you break it down like that, I definitely can live without it.
