I'd do it. You not only have Morales who can play first and back Pujols with Votto gone but Trumbo should be re-qualified at 1B with Morales moving to Seattle and Pujols needing a few days off and switching with Trumbo and DH-ing a little too. So Trumbo can back Pujols too and Harper and Joey Bats are added.
Hamels is good but you got to give to get and Philly is on a downward spiral so short term at least his Wins may suffer. And there are always new pitchers coming up out of the woodwork it seems like Kris Medlen last year.
