I can't say for sure without further looking into the request. At first glance it's somewhat possible, but SOBI2 doesn't keep track of say user groups like remository or docman does. So you can't simply reassign a user to a group that gives them more access. SOBI2 works on an entry by entry basis with its own built in payment system.
What you're wanting I believe would require a custom CBSubs plugin as well as editing of SOBI2, but again I can't say for sure as I've not attempted this.
Out of the box the SQL plugin can do something such as on plan activation publish XYZ users listings. This would work well with "Merchandise". Allowing users to add as many listings as they want (or however many you limit via SOBI2). Then publishing them by purchasing a publish package through CBSubs. This is just an example. SQL plugin is just that, SQLs. It runs a query as if you ran it in say PHP, but it's based of a plans activity (subscribed/unsubscribed).
You can find SOBI2 and other SQL plugin examples
