Make it so changing GC's doesn't reset your PvP Rank

That's fine so long as you permit us to Frontline alongside friends of different GC affiliation, FC mates or otherwise.

If by "alongside" you mean trying to kill each other, then yes. You'll probably have to rely on luck to make it through the DF at the same time though.

The entire concept of Frontlines is the 3 GCs fighting one another for their respective city-state. If you think people from different GC will be able to fight on the same side I would highly doubt that.
