group riverdashboard

I have idea to create a riverdashboard with messageboard facebook like style. This could be a base http://community.elgg.org/pg/plugins/jonmaul/read/458332/group-river it is plugin is showing recent group activity and should be developed a bit to include posts from http://community.elgg.org/pg/plugins/release/607502/developer/webgalli/message-board-with-group-message-board-option)

Anyone could combine this?
