Maybe what that pike pufferfish wesen who made the zombies did to Nick might cause something when mixed with Adalind's blood. But then again, I don't know how Nick's own blood could take his powers away from him, unless Hexenbiest blood does that.

The likelihood that it may be only temporary - Nick took away Adaline's powers before he was zombiefied (not sure the spell recipe accounts for that and may 'kick back' to Adaline, or not work how its suppose to due to the extra addition), then again Juliette also has had NIck's blood, or maybe Mummy Grimm has to return.

The reference from Viktor and 'you have his blood in you' is very open. Id say the spell is more a ploy to administer another concoction to Nick....
