Couldn't they do mountain top finishes on the Gavia and the Stelvio and just Bus them down the other side? Heck they've done this bus transfer bit during this yrs Milan-San Remo already. They're set up for timing at the top of those passes. All they would have to do is re-route the team buses. Maybe not on the Gavia because there's not a big parking lot for all the team vehicles but the Stelvio has all the parking room you need...?
