I mean, it's fairly simple geometry (and not the whole exhaust) - either using shorter mufflers like you said, or, using a more tapered design (like using a 45 off where it mounts currently until it meets up with the end of a shorter muffler, or heck, even lopping off the lowest portion to the ground and creating a bit of a flat spot there, filling it with a triangular piece. The added benefit would open the door for people looking to lower their Z (or G?), can still buy your exhaust, as well as people who have road issues.

I don't think it'd change the sound (or gains) much, but then again, I don't design exhausts.
