I have built several experimental bipole systems.
One disadvantage of a bipole setup is that you will probably get a severe dip in the on-axis frequency response at the frequency where the path length difference from the woofers to your ears is equal to 1/2 wavelength. The dip would probably be in the lower midrange or upper midbass region.
It is possible to design a system that minimizes this path length difference dip (and indeed Definitive Technology holds a patent on one such technique), but you have to design the system specifically to address that issue. It is very unlikely that placing two identical speakers back-to-back would work.
You may still like them in bipole configuration, as dips are less audible than peaks.
