Getting Stroman into the rotation is definitely desirable but you need to make sure he's good to go. You don't want to insult anyone unnecesarily by demoting them for a pitcher whos's not ready themselves. Skipping Buehrle for health reasons and giving Stroman a spot start/audition seems like a sensible play and depending on how that goes, you could make a further decision (the health of both Buehrle and Stroman are the x-factors here). If you can't justify skipping Buehrle (seems like you could but whatever), then you could just put Stroman in long relief and keep everyone but Price on a short leash. That would surely create an opportunity for Stroman to go multiple innings.
