I regret to inform that I have decided to discontinue any Team Fortress 2 Vs Capcom related submissions, and I deeply apologize for anyone who was interested in any of my works. My reasons behind this are simply that I no longer find thinking up Capcom related things for crossovers fun anymore (for now at least), it's just too basic and there's no fun in making move-sets for characters that already have ones made for them. This isn't to say I don't like playing Capcom crossovers anymore, and I'll always be a fan of Tatsunoko Vs Capcom. If anyone was interested in who I would for this fan idea, the roster is below was as follows -
Heavy Weapons Guy Vs Ryu (Street Fighter)
Soldier Vs Chun-Li (Street Fighter)
Scout Vs Viewtiful Joe (Viewtiful Joe)
Demoman Vs Dante (Devil May Cry)
Engineer Vs Mega Man X (Mega Man)
Sniper Vs Leon Kennedy (Resident Evil)
Spy Vs Strider Hiryu (Strider)
Medic Vs Amaterasu (Ōkami)
Pyro Vs Morrigan Aensland (Darkstalkers)
Horseless Headless Horsemann Vs Sir Arthur (Ghosts & Goblins)
Saxton Hale Vs Frank West (Dead Rising)

If you believe that TF2 Vs Capcom is still a good idea, then feel free to do anything with the idea; or if you want advice on how to do it I might even be willing to tell you what I think would be interesting if you ask me (nicely). I may or may not try doing this again, but at this point in time don't expect anything. I'll still leave the two submissions I made for any reference.

Now that that's out of the way, I'd like to say that while I'm not gonna be doing any Capcom related things anytime soon, I'm still very much interested with Team Fortress 2 being a fighting game. I haven't fully decided, but I'll probably get started on either -

Hasbro Vs Valve (Transformers, Half-Life, GI Joe, Counter Strike, MLP: FIM, TF2, etc.)
My Little Pony: Friendship is Magic Vs Team Fortress 2 (I'm a huge fan of both, but if you don't like it that's ok)
Team Fortress: The Fighting Game (Just TF2 characters, will probably have customizable move-sets)

What's really good about these ideas is that since I'm not using the Capcom crossover button layout, I'll be free to put in any features that will allow characters a diverse set of attacks and abilities. While I would have to submit a guide on how these games would be played in my ideas, it's still a great idea that I'm sticking to. Whichever of these ideas would have me most motivated at the moment will probably be started on as soon as possible. So until then, good luck my pals.
