Extending Existing Forced Air into Addition

Hey gang, Im looking to extend my existing forced air ducting system into a 4 season addition that Im building. It will have a shallow ICF crawlspace with the addition on top. I drew out my current system, as well as what Im proposing on a drawing. Can someone tell me if Im on the right track, and maybe what else I might need to do to make sure I dont catch much grief from my building inspector?
