Yes I agree with having Jill back, it would be a nice way to give some back story on some bits Aswell.
Loose storyline such as:
Jill takes on her first mission after coming back to the BSAA, it's clear she's affected by what's happened to her as she is hesitant and a bit nervous.
During the mission she could have (playable) flashbacks to after the Spencer estate incident to give proper closure on what happened. Would also be a great excuse to bring Wesker back even if just for voice acting. Alex could make a surprise visit too.
Depending on what happens in vendetta that could also give more basis for story. Perhaps the mission Jill would be on
