You'll have double overdrive. The problem is the frictional losses go up with a set up like that and can possibly pull the engine out of its best operating range ( you're lugging the engine ), so you have to calculate where the rpm is going to fall when the second OD is kicked in. I learned in trucking that setting up a driveline that is geared to be most efficient in direct can save more fuel.
