Supporter and Multi-Subdomain together?

Hi,

Is it possible to do thing like this?:

As new Supporter version supports different packages, I have such idea - For example, I will create two packages - 8$ and 15$ cost, 8$ will include everything for blogs, 15$ will include everything for e-shops (I mean plugins in everything (which can be sorted with Supporter plugin). But I also want first users to have domain for blogs (in my case - eblog.ge) and second users domain for e-shops (in my case - ecart.ge).

Is it possible?

Thanks
