Custom icon download

I think it would be a great feature to give the users the ability to customize their download. I'm talking about something similar to how you download Bootstrap. I've found a nice tool that helps in the matter - <a href="http://fontello.com/">Fontello</a> - but Font-Awesome doesn't get the updates too quickly there.

Such a feature will increase performance as downloaded files will be considerably smaller. I've put together a mock-up bellow to better illustrate a solution for this:
