Don't forget that, due to Brook's previously shown control over the chess soldiers, any homies not infused with BM's own soul will be useless in the upcoming battle. Also, if you're counting Carrot among the high-profile fighters, you should definitely count Pedro as well, as he clearly showed his combat ability when distracting Tamago and the other guards.

I'm very curious to see Vito and Gotti in action, as well as the full extent of Bege's DF powers. His fortress'll be vital to give everyone an opportunity to regroup, especially when Sanji makes an attempt to save his family in the middle of it all (because c'mon, who's even doubting it at this point?). If Bege can get a few of BM's forces to bring the fight inside him (God that sounds wrong), they could gain quite the home-field advantage, though they'll definitely need most strong defenders to hold the line outside if they don't want to be overrun. I'm counting on Jinbe to hold the line against Katakuri, and Nami and Caesar could definitely lay down some wide-range defenses.

A lot of it comes down to how long BM stays out of it, because they're probably doomed if they have to deal with BM and any other high-profile contender simultaneously. The mobility of Bege's gundam mode could also make a big difference since it's a complete unknown at the moment, though i doubt it'll have much, if any. Finally, there's Mont' D'Or and his book fruit, which is completely OP once you're caught up in it. Unless someone with high observation Haki can see through and keep him busy, he could take out most of the allied forces (lol) easily. This is why i'm guessing Sanji will be the one to deal with that, since kenbunshoku is his specialty.

How they'll end up escaping only Oda knows, and personally, i think it's pretty obvious they can't win against BM's forces unless some miracle happens. They either hold out long enough to come up with a new escape plan, or Oda will have to show his brilliance yet again.
