That is exactly what I am working on with my project Progressive Lawyer. I am using WPJobBoard (http://wpjobboard.net/) and am moving to Avada mainly because GD will be compatible with it. The directory part of the site will be last though as I need to ensure the job board and then BuddyPress part of the site work properly in the way I need them to work and GD is not fully compatible with Avada yet.
