The only character of mine that would say "Yes" to that is Lillian, namely because it would give her a chance to become the best alchemist in the lands.

Bonesword and Abigail would say no, they both want to reunite and live out their lives together.

Frog would say no unless he figured out what happened to Artoria o so long ago, and then he'd say no because he would want to free this realm.

Eve... well... Eve'd say no because her entire race is here, including the guy that she may-or-may-not-have fucked during this entire battle.
