OK, so the first thing I'd say here is that most dualband 2m/70cm antennas are a half wavelength at 2m. The problem comes with antenna pattern nulls at higher elevations, particularly on 70cm. I'd be more inclined to look at either a halo-type antenna for each band or a turnstyle, both of which are quite easily homebrewed.
Secondly, yes you can do it, but I'd be concerned about somebody charging down the highway at 100kph+ focusing on a satellite contact, playing with their knobs and not watching for me as a fellow road user.
