Great idea. This is definitely doable. I've got some code already which can parse a post and determine if it's image, video or audio only which could probably be used. Once we get an MVP out with the basic features, we're definitely looking to expand the scope of this thing well into the future.

Down the line, there will be a focus on having different content types. Steemit and Busy are both heavily focused text, but not so much other types of content.
