I've done it
I had to recore a substantial amount of the deck on my 1974 model. I removed the rotten coring from the inside, the reverse of what is usually done, as interior skin was very thin and deteriorated. The coring will bend to accomodate moderate curves, its basically 1/2" cubes glued to a glass cloth. Many bolts and fender washers held the balsa up while the epoxy cured. Yes, epoxy bonds very well to hair and skin. Good luck.
