Making any major change in a bike's steering system will change the handling of the bike. The Expedition is an unusual bike that is set up to ride in a very particular manner. I would not try to change the geometry of another bike to sort of match that of an Expedition.

One seldom gets off a bike to stop anyway. Most folks come off the saddle, leaving one foot on a pedal and putting the other one on the ground and leaning the bike toward the down foot. To start off, just push off with the down foot. Or you can come off the saddle, put one foot down and then the other. To start off, lift one pedal up with your toe, put your foot on it and push down.
