Personally, I don't think you'll encounter any problems doing this. I just invert the Z on everything (by that I mean I flip the Z axises and translation) and GL happily complies.
Since I intend to eventually get a DirectX renderer into my engine at some point as well, one way or another I'm gonna have to flip it.
