That is cool, Ive thought about it but the budget said no...

Careful with that foam. Closed cell? It could absorb water and really create a problem if not. Also, should there be a problem underneath it it would be difficult at best to fix. I like the peel-ply idea! Is it only used on the final fill coat?
