Selling protected content to members who have access to protected content?

Can I "upsell" content or memberships using the protected content plugin? I want to have people register for free and get access to a dashboard. From there I want people to either become a customer(subscription based) and/or an affiliate(One Time Fee). Is that possible with protected content or any of your plugin combos?

I would also like to use the Stripe payment gateway. That would be a bonus.
