I would have ZERO problems with trimming checklists and altering procedures at AA. I've been on the 777 for a while, and the closed-loop electronic checklist is a glorious thing, so there's very little to be done taxiing out. Weights/thrust, flaps, trim. So I've lost touch a bit with some of the older jets' procedures.
What I don't want to lose is the training culture itself; the school instructors and current CKA group are outstanding. It sounds like US also has this, so hopefully we'll mesh very well.
Slightly OT: We have a couple of guys right here from this forum in school as we speak, in the 8 Jan class. I think it'd be really cool if they started a thread describing the experience, the good and the bad.
How about it, new guys?
