The only MP expenditure is the potential healing from the missing fairy. The rest should be the same even if you don't blow the fairy since in both cases SCH would need to heal. Moreover, since usually blowing the fairy should be used in heavy AoE situations, in those heavy AoE situations the SCH that blows the fairy would consume less MP as it would need to do less cast and would have more aetherflow to deal with it.

The only potential cost of blowing the fairy is the healing after that AoE situation and having to blow swiftcast. And don't tell me that resummoning your fairy is MP expenditure when you get 3 Aetherflow you wouldn't ever get if you don't blow her.
