It won't raise the surface.  You'll be putting the mat and cloth in the 
holes and on the bevel you grind, not on top of the finished surface.

The holes are too big to fill with an epoxy putty, and laying up epoxy 
laminates is a lot less forgiving than polyester.  It also means you can 
never do a polyester repair in that location, again.

I really don't understand why everyone wants to repair a polyester boat 
with epoxy.  Epoxy is not magic stuff.  It has some advantages over 
polyester (adhesiveness, more waterproof, fewer VOCs), but also some 
disadvantages (sensitivity to UV, sensitivity to mixing accuracy, 
sensitivity to application, sensitivity of my hand to the hardener).
