If your DME pick up is at 1:30, you will need to be there between 1 and 1:15 to get your stored bags and be ready in case the bus is a few minutes early. It would be cutting it awfully close whether or not you would make it. If you are prepared to take a Taxi or Uber to airport if you miss your bus, then I would say go for it. If you want to make sure you get on that bus, I would say no.
