I could, but I would have to create roms for all the carriers. The one thing I would like to do (or if someone had the time and ability to do it for me
) is to create an app that lets you choose your carrier upon initial bootup and then carrier specific customization is performed from there. The wizards at xda have this in their 3.3 rom for the Wizard and it is really a great idea. I just don't have the time to mess with it right now.
