Pay Per View and Membership on same site?

I search the site and found this thread but did not really answer my slightly different question.
https://premium.wpmudev.org/forums/topic/pay-per-view-and-membership-on-same-site

What I want to do is have a membership site 2 different memberships
1. access to everything + forum
2. access to everything + + forum + physical mailing

and then I want to allow for single article/post purchases as used with the pay-per-veiw.

Make sense?
