The only thing that would fast track it is if a gun fullback came through the system... or a fullback like an Edwards that is just elite in defence, yardage and good enough with ball in hand.
If for instance we had Iongi coming through the broncos... you could see an argument of moving Reece simply because Iongi is safer and more of a workhorse at fullback.
Walsh doesnt really change his attacking play whether he's at 1 or in the halves... as shown last night he was basically playing 7 with the 1 jersey on.
