I don't recall polyurethane foam melting anything in using it.
I do remember this...it sticks to EVERYTHING!
Gorilla Glue is basically polyurethane.

I would try making the part out of urethane board. They sell it in 1/2" and 1" thick 4'X8' panels. It is covered in aluminum foil so that has to be pealed off.

Once you have your perfect plug. downsize it about 1/8" on the front and sides. Then cover it completely in 1-2 layers of fiberglass and polyester resin.
Of course it wont be perfect but then you can sand it down and build it up where needed with auto filler putty. Eventually it will be what you want and will fit perfectly.
