Any time you put two different metals together you increase the likelihood of corrosion. However there are seals that are used to insulate between fittings to keep the two different metals separated and thus prevent the corrosion. I saw where they did something similar on the show "This Old House." He used a special plastic or rubber seal to insulate between the copper tubing and the steel tubing to keep it from corroding. If you can insulate them and keep them from directly touching each other you can keep them from corroding.
I'm not sure how much of a difference there is between galvanized and mild steel pipe. I imagine some, but probably not as much as with copper and steel. See if you can find an insulator to keep them separated, then you won't run the risk.

Galvanic reaction. Wonder if a current could be possibly sent from the passive metal to the more-active metal?
