Supporter plugin, users only have to pay once and can create as many blogs as they want

Hello I have looked into bulk upgrades and pay to blog already
and search the forum for some bit of time

and would like to know if and how the supporter plugin can be modified so that the users can register as many blogs as they want and only have to pay one time, the monthly subscription only!

I cannot use pay to blog since I want to have supporter so the users can register a free blog and see that they can get premium themes and plugins and more features which are blocked and provided through the supporter plugin

if there has been a fix to this or been told about before please link here!
I would like to get this solution up right away!

thanks
