Rod Woodson, who is a playable cornerback legend in APF 2K8, also played free safety later in his career.

It's not unheard of for corners to play free safety.

Moving corners to strong safety would be a big stretch, though. I can't think of any examples where that has happened. Usually, the alternate position for strong safeties is linebacker. I remember Jermaine Phillips having recent success at both places in his career.
