I suggest you read that thread. A lot of the suggestions in there are very good, some of them are just not very well thought out. I started to piece these together back when that thread was active but I ran out of time and motivation.
I believe Hoonsey's work that your talking about is the BC-Spells patch for Mazzle, and that already has a few perfectly good working layouts in there: particularly the Paladin and Warrior layouts I know for a fact work very well.
I'm leveling a priest and a rogue right now and I know I would appreciate having level 70 spells already in layouts for when I get there, so yes this project is something that people (myself included) would be interested in having uploaded.
