^^^ Hahah, if one could do it, perfectly though, it would be funny the “old” AT-AT does shoots down Finn’s speeder when the “brand new ones” can’t do it.
But doesn’t one of the new AT-ATs shoot down Finn in Poppa’s version? If you animated one of the old AT-ATs, then had one of the new ones make the shot, it would cause a continuity error.
I personally don’t think the idea is necessary. It seems like way too much work for almost nothing. Finn’s crash comes out of nowhere in the theatrical version too, so it’s not a big deal for me.
