Offset bipoles can help smooth room modes but still won't make the bass go lower, just louder. You wouldn't want a fullrange mounted too close to the floor or it will sound bass heavy. Subwoofer yes, but not a fullrange. Hmm, there are some open baffles using a fullrange close to the floor though now that I think of it. They wouldn't have much bass otherwise but that doesn't apply normally.
The AudioKinesis forum on Audio Circle has some good discussions on late ceiling splash (LCS) and in-room subwoofer integration efforts. Duke LeJuene talks about his Swarm system in several posts. See his web site for his products.

Full range offset bipole as designed by Jim Griffin http://p10hifi.net/planet10/CSS/EL70/Griffin-offset-bipole-mltl-100909.pdf
Given how close the Pluvia 7 is to the EL70, i suspect that even thou EL70 is sadly NLA, his design is not obsolete. The P7 has been a straight drop-in (or only very minor adjustment) into the EL70 designs we have checked and Jim’s designs tend to be pretty tolerent so i expect P7 will drop right in.

Wrong, not lower, just more of whatever is there below the crossover point.
If the distance between the 2 drivers is less than 1/4 wavelength, it won't matter. @120Hz, that would be about 71cm or 28 inches.
You'll only get deeper bass if you use a driver that goes deeper than your fullrange. But that's not a 1.5 system, that's a 2-way.
