I would stay south, forget about riding home to MI. Better to enjoy the actual trip than avoid a day or two and a few dollars of expense getting home. Early September is about as late as you want to be in the Rockies.

You might consider taking the Southern Tier, then turning North once you get closer to WI's longitude. If the weather turns nasty on your way north, take a bus the rest of the way. If not, ride all the way home. Just a thought.
