Feel that this question is the one that club should be asking themselves. Be interesting what the majority of the site thought.
Rebuilding would mean seriously looking at cashing in on our Elite players currency to create a list around Martin and Prestia's age bracket. Deledio, Edwards and Cotchin would be the main traders as KP players don't grow on trees and are harder and take longer to develop. We could keep Rance who in 3 years time would be 29. Jack would be 30. We would move on our middle tier almost instantly and look to play as many games into our 'iceberg' players such as Castagna, C.Moore, C.Ellis, McIntosh, Markov etc.
Negatives of this is excepting current list isn't good enough and 2-3 years of bottom 6 finishes await..
Rearranging would be potentially moving some middle tier around if possible but certainly not our top tier. Our middle tier haven't got much currency to do this but with luck and the right calls could possibly work. Holes would need to be filled at all cost, eg: need a ruckman, noth key back and key forward to add quality in the arcs as well as some more leg speed and kicking efficiency. Ideally tackling a focus as well.
Trading in 'moneyball' type players possibly at the expense of future draft picks and players.
Negatives of this is if this doesn't work we would be wasting Prestia and Martin potential juggernaut midfield with having Cotchin and Deledio retiring with no 'blue chip' draft pick replacing them.
