Possible for a subgroup that users can sponsor someone to update/create addons?

personally i could only afford more than 10usd,
but if many want that feature, many people sponsor,
someone found it also useful and with reward, he/she may update/create the plugin.
(the release plugin would be FREE to ALL, however)

money in society is like electricity in a battery, it drives things.

programs shift from closed source to FOSS or commercial and switch back sometimes).
