The Twins may not be adding any six-year free agents this year. That is hard to believe, but those deals have usually gotten done by now and the Twins have a lot of their own organization players who need spots to play. So where does that leave Rochester if they don't add any veterans to fill out the roster? Obviously some of those decisions will depend on who wins jobs at the major league level. The other issue, aside from the players themselves, is moving up to New Britain from Fort Myers. This assumes that Morales and Pridie are on the major league roster. It also assumes Tolbert, Harris and Casilla are either on the roster or elsewhere if the Twins add another infielder.
Ramos could by move up to Rochester, but I think they will want both he and Butera to play regularly. Lehman is an organization guy.
Erik Lis and Whitney Robbins will move up from New Britain, in part because Parmelee and Leveret are both ready to move up to New Britain.

The pitching staff will likely be decided by playing musical chairs in spring training. The losers of that competition at the major league level will fill out the roster in Rochester. This assumes that Liriano is the fifth starter and that Nesheck, Keppel and/or Perkins take the last two spots in the bullpen.
