This would be awesome. I bought a theme off of themeforest the other day and they essentially wrote a mini-cms in js that would have been way to much work to tear apart and turn it into a static site.
This morning, I'm working on adding a grid framework to another theme I bought off of themeforest. That's the one thing I hate about themeforest is you can't see the "bones" of the theme before you buy. I've bought 4 or 5 themes off of theme forest with about 3/4 of them being of decent quality. With decent quality being the ease at which I can modify them for my own needs.
