Is this an AA award on a single ticket? You said "Primarily an AA issue." I don't know what the published international-to-domestic connection time in CLT is, but if 2:15 is genuinely tight, AA will likely be very accommodating on creating award space. However, if the incoming is not on AA metal, they have somewhat less flexibility.
The best thing to do is look at schedules and decide what you want, then call AA and ask. Your request isn't ridiculous, it's not like the connection changed from 4 hours to 3:50. But it will be helpful if you know what you want rather than asking AA what they will give you. Don't confuse the poor agent.
