Of course, which is what makes it worth looking at. 
I'm going to say that the needs of full armor
protection and the requirement to be controllable at
the 2-3' altitude require slower speeds overall. 
YMMV.  The problem with vectored thrust or turbines is
that it reintroduces a requirement for fuel (reaction
mass, actually) and that's what we're trying to avoid
by going to grav in the first place.
