Oh no, not in Avengers 2 - in X-men 4 or 5 but they would need to introduce Carol in Avengers first obviously for the mind wipe to have any real meaning. I loved Rogue in X-men 1 but she was a bit superfluous in 2 and 3. She needs super strength and flight and somebody else's personality in her head to make her interesting again. There were even a few comics where Carol's consciousness took complete control of her body. I don't think that would be lazy story-telling though - it's a classic part of the characters' history with quite a lot of potential.
