So I've had a bunch of time to think about it. Here's how I see this going:

-Teams don't meet immediately. Bowser's starting point is fairly fair away, and I think out of both teams' engagement range. This means Mewtwo gets to buff up and possibly apply buffs to DK too.
-Raiden is super beast. He's the best combatant on the field and I don't think it's close even with buffs. I don't think he oneshots people though. Diddy and Dixie, sure, Mewtwo if he gets in on him through his barriers, but Bowser will take at least a little bit and DK will take longer.
-Gordon's a significant issue. Nobody except Mewtwo has range to check him (I suppose Diddy could jetpack towards him and jump on his face or something? But he dies quick if he tries that). It's an open question if Aria's team gets in on him or not. If they do I think he dies and clears the way for a 1v5, if he doesn't I think he gradually picks people off.
-Bowser is super important here. Terrorize buys time to actually fight Raiden off, and if Poison Gas connects and poisons him, it puts a super hard clock on this match. However long you see a Super Mario RPG turn lasting, Raiden will get ten of those max before dying on a successful poison implementation, and Mewtwo can scam that time out if he focuses wholly on flying and not attacking. He has no robots to heal off of here. Additionally, if Bowser gets in on Gordon, I think he probably wins thanks to Mewtwo's healing.
-Mewtwo and DK are both required to deal with Raiden at all times. One isn't enough, at all, and I think if it's just the two of them vs Raiden, Raiden eventually wins.

Essentially, this match swings on the axis of 'who dies first? Gordon or Bowser?' I think in a slightly less open terrain, Gordon takes it easily. Splitting Bowser up enough that Mewtwo's healing sprinkles can't hit him is all it takes to win a (somewhat) protracted battle, but this terrain is very open, and while Diddy isn't great, he can at least distract Gordon long enough to give Bowser a chance to reach him. And if that happens, I think he can then start debuffing Raiden hard and putting a clock on him. It's a very close match, but overall, I think his team wins.
