I'm currently working on making a Hulk model that's useable in-game, I'm still working out the little animation stuff on it and in a couple of days I'm getting a graphic pad and doing the texuture from scratch.
BTW if you have any mannequin requests feel free to ask, just mention the character, the skin and the pose.
These aren't "requests" per se, but here are the mods we have in the catalog that don't have mannequins or (in my opinion) could use an improved one. I sent the same list to Overload, so hopefully you guys can coordinator your efforts!
Rhino - This mod already has several skins, so a manny would make it that much more complete.
Multiple Man - current one is a reskinned iceman
Magma - needs improved, has some black dot issues
Pete Wisdom - Model is turned facing the far left of screen
Holocaust - none
Gladiator - none
Now on to requests! Personally, I'd like to see mannequins for some of the XML2 mods that are available, as many will surely get converted to MUA at some point, especially Blink (can't wait to get her into MUA), Forge, Marrow. I'd also like to see an arrogant-looking Quicksilver mannequin, Abyss, Bastion, Lady Deathstrike (the last three being mods I've started and might get around to finishing sometime).
Again, just some--or maybe a lot!--of suggestions.
EDIT: For skins, I'd go with which one the modder used as the first skin. If you have questions, ask, as I can load all these mods quickly with HeroSelect.
