Allow user to select a theme to install when they signup

Is it possible to allow a user to select which theme they would like installed from the new site signup page? And once the site is created, it obviously installs whichever theme they chose.

I am setting up a new WordPress Multisite instance, and am still working out some kinks in the stack.

As a result, several usernames are stuck in limbo as the confirmation emails necessary to activate them are lost. For now […]
