Meh. Roughriders have Gravity Bombs anyways. Not as refined, of course, but they get the point across. *Evil Grin*
But really, I suppose you could simulate the effect at a much-diminished level and apply it soley to the surface... but it still does nothing for the magnetic fields and I bet it'd be rather energy intensive - which is something not desireable since power failure can mean slow death for everyone not close enough to an emergency shelter.
EDIT: Bob, regarding seismic activity in reaction to increasing Mars' core gravitational pull, it would definitely be something not to take lightly, but it may be manageable. Really, it may be rather desireable since a seismically active world is one capable of self-renewal over time - and unless I missed my guess we want Mars to be able to sustain humanity life for the long-term.
