The challenge for Tasmania will be convincing players to move down there. After watching Gold Coast and GWS struggle so much early on, most established players will probably not be that excited unless Tassie pay them ridiculous amounts.
I believe that when one of the one of the earlier expansions clubs was brought in teams were asked to nominate their 'best' 22 and the new club had free reign outside of that. It's not a bad way to build strong depth and perhaps players not considered in the best 22 may be happier to move. Add in a few elite free agents or trade acquisitions and high end draft talent and it might work.
