The main problem about the roamer is that unlike previous seasons, it's not possible to stack gp5s and make do with them alone. While gp5s were ticking wherever you were, the new support items provide a large portion of their gold though interaction with lane minions and/or enemy champions. The roamer you were talking about would be heavily underleveled and underfed (and we're talking like half the exp and gold of a support) therefore causing teamfights to be essentially 5v6 (5v5 at best if an enemy roamed as well). This might be solved partially by taking Targon's (the stacks build up over time and can be utilised in rapid succession) - keep in mind, however, the experience loss is still an issue. Only a select few champions can provide reasonable utility when both underleveled and underfarmed - mostly the displacer supports, like Blitz, Alistar and Thresh. Then again, all 3 of them can do even better if placed as a support, therefore making the role of a roamer questionable at best.

Personally I'd think more of 2/1/2 1J or 1/1/2 2J. Dual jungling would be brutal, but there are champions that can make it happen (I'd think Fiddle and one other; a Trundle could do well in this setup, given his insane 1v1 potential vs ad bruisers like lee and udyr - but maybe that's just me). For dual top a displacement support would be awesome - in bot the other player can save you or capitalise on enemies overcommitting to kill you after a grab/hook/headbutt, while on top you might be on your own.
