Well the problem lies in the fact that the polyester gelcoat would not stick to
the epoxy.

You will have to use poly. I won't stick as well, but will have to do.

Gelcoat is purely cosmetic and I'm far more concerned with the strength
of the underlying repair, so epoxy gets the nod for that. I've applied
gelcoat over epoxy repairs and it works fine as long as you sand the
epoxy surface.
