wakeskate diy idea!

ive been given a wakeskate to try,and while i was looking at it i had an idea,i can get 1" or 2"  eps sheets with pvc either side(upvc door panel infills)  what about if i used one of these,shaped it and wrapped some glass around it,im aware id have to use epoxy(whitch i havent done before....but ive done lots of pu)   any ideas if  the epoxy will bond with the pvc or not,maybee rough it up a bit?

 

 thanks in advance!
