I certainly think it is a possibility.
While Gailey has been known to run a "spread" offense as a HC, as a coordinator he has really been pretty flexible, depending on who he was working for. He has been with teams that employed a man blocking power scheme, as well as those that run more zone blocking.
I don't know if this is going to work out or not, and my first reaction was WTF, I have since looked more closely at his history, and came away with the impression that he has coached a few different styles of offense.
