Integrating /w Existing DB (more than Membership)

I see quite a few threads regarding integrating ASPPlayground.NET with existing membership providers, but I'm specifically trying to integrate ASPPlayground into my existing database itself.  I have much more than the default membership in my database so I'd want to completely merge this database with the schema/SPs/etc from ASPPlayground.

This wouldn't be a big deal if my host didn't charge for every extra database (regardless of size), but that is how DiscountASP operates.
