Bugger Ellis, has a body made of tissue paper, it would be Xavier Clarke Mark II.
If we're looking at realistic unrestricted free agents (i.e not Sam Mitchell or Jobe Watson), why not Port's Tom Logan? Only 28 next month, strong-bodied at 183cm and 85kg, and can play forward and on-ball, although primarily a back pocket. Could be handy to put a bit of grit and bulk in alongside the kids, and to release Nat Wright further up the ground.
