With the exception of the larger Apogee planar speakers or arguably one of the hybrid models, most dipole speakers simply can't provide the same bass slam as a cone driver.
If you can't upgrade to the larger Maggies due to the WAF, then the Apogee route is probably not an option unless you can find a pair of Cepheus 6s. Try before you buy.
I like the subwoofer idea. It shouldn't be hard to integrate a downward firing sub (or pair, if you have the space). If your floor is wood or concrete, you'll be good to go. If carpet, place some wood floor tiles or (better) a stone or granite tile under the sub.
Finally, if you are determined to replace your Maggies wth something new and with a similar (dipole) sound, I would suggest that you look at the DECware ERR or maybe even the Ohm speakers.
