There's some definite advantages to this when the XO point is > ~1 WL away from a dual driver's acoustic center and you're not far enough away from the speaker(s) to make it a moot point, so at a glance the way around this is to either use a vertical MTM or horizontally opposed layout depending on the app.

WRT mids confliction, I don't recall this ever being an issue with either the 500 or 800 Hz versions using horizontally opposed woofers plus it has the advantage of being able to control directivity to a lower frequency in the horizontal plane, so if the space permits, this is my preferred dual woofer layout.
