Not sure it would be a good move. He isn't going to play Saturday, Tuesday in the Championship and he certainly hasn't got the legs for midfield. Maybe he could play in a back 3 (where he started his career at Villa.)
He isn't also much of a leader IMO. Those seasons when we were chasing 4th with O'neil, we drew so many games towards the end of the season and Barry never stepped up and banged one in the top corner like a Gerrard or Lampard would.
Nice guy, good pro, lovely player at times but not a real leader of men.
