Wow man, that sounds pretty crazy. I understand wanting to salvage your baby, but shit, that's a lot of tedious work. A lot of work even for a professional. Good luck.
If I were you I'd chalk it up to a board well used, head down to your local snowboard shop, and support the economy in your home town.
The last thing you want, is to be on a trip and have that edge pop out in the middle of a beautiful day and have to either call it quits, or try to find a board you want in whatever shop they have nearby.
As a fellow "DIY'er" I say again, good luck.
