	Perhaps by throwing off collision detection, but there is a
	more basic problem:  If you do this, it will no longer be a
	50 ohm impedance!  This will, of course create/exagerate any
	problems you would normally encounter with reflections and
	standing waves.

	In short, I recommend against it, HIGHLY.
