Use geloat over epoxy if you care to do so. You just have to do a lighg
sand on the epoxy so there is some tooth there. You have to do the same
with polyester or vinylester, because the cohesive bond with gelcoat
(which is also polyester) is poor (lust like any other polyester).
The only advantage to a gelcoat finish on a repair is that it is
relatively good for a color match and as it is applied thinker than any
paint, it can be wet sanded to fair the surface.
If you were planning to paint anyway, blow off the gelcoat job.

Don't use gelcoat. LPU paints weather better and are easier to work with than

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.
