So I got an idea. For Adventure maps, you can't really customize the look of the mobs all that much. Using Sethbling's Player Skull Filter (http://www.sethbling.com/downloads/mced ... yerskulls/) you can use player's heads to suit your needs, but what if you don't have a server, you need the player's .dat in your world file. But! What if everyone who would be fine with other people using their heads put their [player].dat up for download? Then you could just visit this forum, browse skins, then pick one, download it, and use it for a world?

Post using this format (replace what's in <>)

MC name: <Case sensitive>
Skin: <What is it?>
Picture: <Picture>
Download: <Download for [player].dat>
Terms of use: <Can I use it in an Adventure map? Video? etc. And can I use the name?>

If you think this is a good idea, spread the word to other forums.
