Sounds interesting I run mid scale news websites in WordPress all day with paid content feeds, multiple contributors, custom post-types and taxonomies...at a cursory glance this sounds like it might help. The real issue will be time to integrate. Right now we are moving from yellowbrix to acquire media and the process has been fun : ) (not) We use PDO to load the feeds and make it all work with WordPress - would your system use core WordPress functions? At our scale and post volume transitions are time sensitive...
