That's entirely up to Dihan. I used a couple things from MUA2 to update an old mod of Gambit I did, and right now Dihan was working on Gambit ala MUA2 style. I don't want to release mine and step on his toes. Mine was more or less for personal use anyway, but maybe in the future or something. Dihan is working on one so you can look forward to his for sure. Mine is about 95% complete, I just have to finish a couple minor things like the loading screen and character specific items. But I have the comic mission, sound sets, 100% working powers and effects, character skins, HUDs, etc. all done.
I'm also planning on doing custom meshes further down the line but that won't be for a long time, which is why I got the skin done now to hold over until then. The one I did a couple years ago was just a quick reskin (and it wasn't that great to be honest, it was just a quick job on the PC model) and was never actually meant to be "released" but some how got included in the big XML2 character pack anyway. This skin is by far much better and I may at least release that, I'm not sure yet. Again, Dihan is working on Gambit so I will wait to see what he does. Not that ours will be exactly the same, but it's Gambit... it won't be that vastly different either. Time will tell.
