How are you going to implement the rectifier, though? The usual implementation is using diodes, but that means you lose twice the diode forward voltage to the rectifier. Even with a Schottky diode that means you are losing 0.5V-1.0V. That's a 10%-20% loss at 5V! You could use a transistor-based "ideal diode" solution, but that's not going to be cheap - especially in the 90s.
