One, your suppostion of the 90 degree total phase shift between the two sections is predicated on the 1st order filter working correctly.
The only time the 90 degree thing occurs, is when there is a resistive load. Your recitifer bridges and filter cap banks would not exactly fall ito that category.If there were a significant resistive load placed across the bridges to try and force a mostly resistive function so the crossover would actually work as intended, then the inefficiencies would skyrocket.
Two, the sheer size of the crossover components would be costly, to say the least! In order to draw current, and be safe and reliable, the caps would HAVE to be film types, and the inductor would have to be capable of huge currents, hence a large core, and even larger copper wires!
The space taken up would drive up the cost of the chassis, etc. and so on.
OK, I will quit now.
