Community Edition premium pricing

I really like funnels, but for my small webshop (local and most orders are through the phone) it does not make sense to pay 39$ for having funnels, and even the 19$ would not worth it. Those who self host most likely wont pay for the full feature anyway, it may be a good idea to allow community edition users to use premium features for a few $ or even a one time payment license. This way CE users would support the project, but still use their own infrastructure.
