My C-5 unit had, get this, F-4, F-15, A-10, B-52, B-1, KC-135, KC-10, T-38, C-130, E-2, E-3, A-6, and a U-2 guys. It's more a matter of you and the unit than anything else. I did help a guy get back into the C-5 after being a T-6 IP. Fly what you want, military experience is usually enough on its own and you'll have a tour and some command time when you next PCS.
