combine Module Membership Plans & Donation

I would like to give a possibility to subscribe two different plans or to make a free donation with jomdonation, whose amount must be free and higher than the two other plans... with special advantages.

I cannot do this for two reasons: 1) no integration with your other own product: JomDonation 2) no possibility to make a free donation with a minimum amount.

I tried to join it through an Article, and an extension (Modules Anywhere) to put two modules in one Page Layout. But it is still a very incomplete solution for my needs.
