Custom Project Folder Icons for OSX

For a while now whenever I start a new project (or months later) I have been trying to make a custom folder icon for it that matches the look and feel of OSX icons. I'm a very visual person, so this is a great way for me to easily jump to where I need to be.

I've been using the (now discontinued) software Iconographer to edit the icons. It's a nice piece of software but it's a bit of a process to do for every project. 

How nice would it be if it were built into osx? It could be as simple as just renaming a file to folder.eps. Apple, are you listening? 

Does anyone else do anything similar? I love the organization, but the maintenance is starting to take it's toll.
