Buddypress Groups - E-Commerce

Could you guys develop a plugin for Buddypress that allows users to create their own little shop inside a group?

Something I read about: https://premium.wpmudev.org/blog/free-plugin-integrates-wp-e-commerce-with-buddypress-groups/

But maybe something more simple and easier to use for members them selves. Option to put in their own Paypal settings and products with prices. This way we can use this as a powerful marketing strategy for our members.

Without installing a E-commerse plugin with tons of options we dont use
Just a small add on to the group, like Docs.
