If Arcia returns to his pre-2015 self we will want him in the lineup every time the other team has a RH pitcher on the mound. Moving Plouffe to the outfield instead of Sano is not going to happen. As has been stated elsewhere, (by Seth, IIRC) Sano is faster than Plouffe and very athletic. I doubt very much that he, at this point, is as good a 3B as Plouffe. Makes no sense. The Twins have a lot of young, inexpensive players. They could go out, pay for and get a proven, effective LH for the bullpen before all the good ones are gone. (are they all gone already?)
