Asymmetric shape of cones and domes. Would it add to distortion? The cones for instance have less drag in the negative going signal since it is spearlike while on the positve going signal the drag is high owing to the parachute effect of the cone.

I was wondering about that... but with midrange and midwoofers, you don't want the basket assembly exposed in the front due to air turbulence and diffraction of sound off the magnet/structure. That leaves you with a pair facing in opposite directions sharing some small enclosed airspace - likely a short tunnel type of thing. But then there is a resonance when the the distance separating the two equals half the wavelength at that frequency... which might well be in the mid/upper-mid region. I suppose you could use a notch filter, but then you have to wonder if the final result bought you anything at all in terms of reduced distortion. It would probably buy you reduced power compression at least...

Why not limit the negative going signal so that you don't need ti invert the basket of one driver.

What you're talking about is either isobarik or bipole; I've heard very good things about both sounds, though I've never built my own.
Really, though, once you get up past 150hz, unless you're playing *LOUD*, the excursion on most drivers is so small it really won't make a difference that the excursion is nonlinear in different ways.
