Any models of mine you think would be improved by a V2 before Kohya is gone?

With the old trainer being sunset I wanted to crank out a few V2s of my older models with poor tagging (generally overtagging, though some I've gotten new training data on a limited data subject) over the next weekish before it's eventually removed (no idea when that will be). I've got a few in mind already, but want to hear what others want. Can't guarantee I'll do them (I might not feel I can make a major improvement, or extra data might be a pain to grab), but wanted to hear if there's anything else I should try.
Edit: Might as well mention here that I'd make a V3 of Sarah Anderson if I had any concept art pictures of her from the Outlaws remaster's vault (or confirmation there is none of her there) if anyone has it. I'm not going to pay 25 bucks for a game I already own just to make a V3.
Edit 2: I'm still working on these. Got a list of a bunch of early models that could use an update. Got over a dozen left to do as of writing this but still feel free to request one. Likely won't do any of the many costume ones since they kinda dependent on their tagging style to work
