Multisite Marketplace with Pro Sites

Hi,

Two questions.

1. I would like to start an Etsy like site. However, I am not interested in selling products myself. With the current Marketpress setup it seems my main marketplace page will look bare unless I add products. Can I fill the page with featured products from other stores instead?

2. Can I use pro sites to establish a subscription service that would allow a free level of store owners to list 10 products free and a pro level to charge monthly for more than 10 products listed?

Thanks
