wouldn't it make sense for crawford and pacquiao to reach a deal at a catchweight?

if bud wants the fight at 140 i don't see how that should be a big deal for pacquiao. didn't he express interest in going back down to 140 anyway? team pacquiao have also stated in the past that they only really fight at WW because that's where the money is at, and that he can easily make 140 still. in fact that would be his idea weight to fight at.
