A higher dispersion is not necessarily the most virtuous trait. It has its merits and demerits. I find it especially irritating when the waves bounce off nearby surfaces causing innumerable reflections. This is more of a concern for car audio than in home audio. I also tend to find speakers mounted in the dash, right up against the windscreen, sound honky.

I don't deny of cone midranges with back cans but they really don't exist in car audio and also mounting them will be pain. Unless youi want to go DIY with drivers intended for home audio use.

Canton cone midranges from their 3-way car audio component set are provided with rear chambers so as to suit the driver's capabilities. They are not terribly deep, but there is no comparison of their mounting depth v/s that of a 2" dome midrange.

You can use steeper crossover slopes if drivers have good flat response curves and are placed closer to each other if they are far off from each other its better to have shallower slopes but all this playing around is only possible in active system

If your driver has a nice and flat response curve, it's all the more reason to use a lower order crossover than say a 3rd or 4th order crossover. You'd want to savagely terminate a speaker's reproduction range only when the driver is known to create some mischief in the band that you are trying to eliminate. So, the greater the break-up or some undesired dips or surges that the driver exhibits, the steeper the crossover slope so as to attenuate the driver at those frequencies to the maximum possible extent.
Also, I see no connection whatsoever between the slope of the crossover and the relative placement of the drivers. It would depend more on the respective crossover frequencies rather than the slope.
