I really don't know, since this is just an hobby for me.
i'm currently working on a PSP version similar to this one, but with more wrestlers and maybe (if i can fix all the bugs) also with some replaced arena... but since Svr10 lacks a lot of the "plug-n-play" tools made for Svr11, sometimes things are a bit more complicated and it take so much time to mod things. Plus, i'm still learning a lot, and some things are just way beyond my level...
If i release the next version of this mod, i was thinking about replacing every "divas" in the game to free around 10 to 15 character slots. This would allow me to import almost every male superstar from 06-2011, including managers (like Paul Bearer and bischoff), more legends (like Snuka and Steamboat), more tags (like the Hart Dinasty) and some alternative costume (tony, masked man, etc...).
but I know, removing divas may not be a popular opinion for some people, so i'm not sure if a "diva-less" 2.0 version is really worth the effort...
