no way man, its a good idea! I had the same and implemented something like that. I had written a script to scan designated directories and cp specific files to a scheme directory. Then the opposite to put back in place. I would run the script manually if I had a scheme worth keeping, dump the ingrediants into a tmp diretory, and manually mv to its final resting place. Hadn't yet implemented naming, creating, and pushing that final directory, but it was on the bucket list. Generally you're looking at a few files

• scrot for posterity
  .Xresources
  the wall
  the sourced color file if applicable
  wm config
  

That's really all that's necessary to relive an old scheme. The project has pretty much been shelved but maybe I'll get back on it. Haven't had as much of a need for it lately. If anyone is interested I'll try to finish it up and share out.
