Template Provider for Setting a Theme

Can the SPA Template provider apply a theme after a site is created?

We are aware that we can use a site definition to do so, however different business units require different themes apply to their sites. The themes are not the standard out of the box. So for every site created, an administrator of the site apply his/her theme accordingly.

I was hoping to find out which template provider could assist with apply a theme after the site is created.
