Same! A Rhodonite flashback would be so cool to see! (Edit: I just noticed that Rhodonite’s bottom eyes and her gemstone are missing in the picture)

A flashback showing how Lars and the Off Colors managed to steal the Sun Incinerator and escape Homeworld.

^ This and of course Rhodonite's love story because I remember reading the concept which was ultimately not put in the show. I think it was going to be in a Future episode. It was avery interesting concept and you can find it on this wiki if you want (I think it's on Morganite's page, the gem who owned Rhodonite's component Ruby and Pearl.)

Ruby and Sapphire's love story was done so well, I would love to see what they do with Rhodonite!

And I wanna see Rutile's flashback but just because I'm curious what a normal Rutile looks like.

And of course, who Fluorite's components are.

Padparadscha's flashback can give info on what happens when a high-ranking gem emerges in a kindergarten (my personal theory is that considering rubies and sapphires are the same mineral irl, in SU there is a very rare chance that in a kindergarten made for rubies, a sapphire may emerge in spots with the right conditions.)

Rhodonite unfused and fluorite unfused the off colors with more personality traits and powers

^It'd be interesting to see that, maybe them unfusing strategically to get out of situations (like Garnet has done on occasion)

While Rebecca's doing that, I'll be reviving the classic steven universe series and making a reboot as well
