What kind of music do you listen to? If you like soft, relaxing, low intensity music with simple yet abundant vocal work, played at low volumes, you probably really like your Maggies.
If you listen to dynamic music with demanding and driving bass lines, lots of macrodynamic action, maybe even use the speakers for HT, enjoy real world/concert level volumes at over 100dB but don't want to sacrafice any transparency over the planars, the Vons would me a huge improvement over what you have and I would suggest the swap. All gear selection comes down to musical tastes.
A caveat, the VR3's MUST, and I mean must, be place no less then 8' apart and no less then 2' off the rear wall to do their magic. Ideally I've found 11" apart and 5" off the rear wall, with measurements in realtion to the tweeter, to be ideal, though I realize similar requirements exist for the maggies as well, so if they work in your room the VR3's should as well, though the room will make for "interesting" bass reproduction.
