Jon,
I drove a fuel truck for a number of years which was equipped with a brownie. I don't recall that the brownie was synchronized. The main box AND brownie required double-clutching.
Even if this were not the case, I think a electrical actuation of the box would be much to instantaneous and severe for it to work properly.
A Eaton two speed rear end does have a electric motor, but it's speed is reduced through a screw drive setup, and that in turn only winds up the spring that actually does the shifting.
Having that second stick poking up through the floor boards is the true mark of a double-clutching Mo-Fo...I would keep the stick and utilize ALL the gears the brownie had to offer.
