I am unaware of any gel poly product. Maybe you are referring to Minwax Poly shades where the polyurethane is tinted. I think that product is water based and will not be absorbed into the waxed floor, making a colossal mess.
You will regret doing that. Why? Because the stain will not adhere to any of the finished areas of the floor and will just pool there and may remain sticky. Not good.
Unbeknownst to me, my cleaning lady was getting the knotted fringe on my dining room rug wet every time she mopped our wood floors. When the rug was removed, there were water stained outlines of the rug tassels on the oak wood floor. UGH! Rather than refinish the whole floor, I decided to use an electric palm sander and sand the stains out and then continue sanding to meet each individual board that was effected. Some floor boards were 3', others up to 6' long. This way there was no fine line where the sanding began and ended as I sanded only the individual floor boards that were effected. Then I stained them with Golden Oak Minwax stain. I wiped any excess stain off the floor, then, using a foam brush, I only polyurethaned the sanded boards. Worked like a charm.
So, perhaps you can gently sand the effected areas and carefully restain, then add a coat of wax. Adding a poly finish to a waxed floor is a recipe for disaster, don't do it. It will backfire and you will be stuck with a colossal mess.
