I debated adding an extra layer to the hull of my canoe - didn't do it due to the same fears. After the outside of the hull was epoxied with surprising ease, I decided to add "ribs" consisting of an extra layer of 6oz cloth (8" wide) every 18" on the inside for additional rigidity.

I laid out the cloth for the ribs, then laid another 6oz layer over that, and wet it our all at once with no clear coat. I had to spend more time working the epoxy through the places with two layers, but it was pretty easy to see the cloth go really clear when the epoxy was throught the cloth into the wood. The ribs are essentially invisible - if your double layer is smaller than the entire hull, be sure to put the smaller piece on below the full sized piece - that way you aren't fighting loose strands of cloth.

He's a stud - I don't know how he can get that to work - I know I'd make a mess trying that.
