Like the Enies Lobby or Wano 'Assembled' square offs?
I wonder. It's all about presentation and if he can do something new.
I mean, they'll all be squaring off, but not in the same location. I find it hard for him to resist the CP9-style approach but it also might be tough to explain all of BB's crew in one place at that kind of pivotal moment.
So...it's possible he could even colorspread it. That would be interesting for sure and he can play with it as he likes.
But will evvvvvveryone show up and 'assemble' for the cause? Yep. Just a matter of realistic placement. I think what's most realistic is a contiguous series of b/w spreads, similar to the FMI finishing-move bonanza but instead with square-offs.
(Look for this theory to be duplicated elsewhere w/o credit on a Youtube channel near you!(^○^))
