From what I have heard, there can be a bit of a disconnect between Rotc and academy students. If the point is to bridge this gap, perhaps it would be better to have ROTC members participate in some of the summer training programs with the cadets.
Semesters in sister academies make sense. Academic and military standards are similar. A semester in a mainstream college with rotc, seems to be asking the academy cadets to take a step back. It would not be an equal exchange of experiences. Not all college education is comparable.
Though some cadets may see it as a mini vacation....sleep late, take naps, have something other than chicken to eat, date fellow students (better guy/girl ratio), casual dress, no mandated football games(fall only), come and go as they please, less limitation on Internet acess, better cell phone service, no mandated lights out/closed door.......
