Two otherwise identical 2 phase ac sources are 90 degrees out of phase and you want to convert them to a single dc power supply.
Is it possible to simply use two bridge rectifiers, one for each ac source and then connect the + output from one bridge to the + from the other, etc.?
Assume the variation in dc voltage isn't an issue as it should be attenuated somewhat anyway.

Yeah, that's a two-phase rectifier. A three-phase rectifier has a FWB on each of three phases, each 120 degrees apart. Two phase is two pairs of wires, one 90 degrees ahead or behind (depending on your point of view) the other. Since the peaks do no coincide, it will work just fine.

It works fine as long as the two sources of AC are either isolated from each other, or all ends equally swing positive and negative around a common node.

Yes, you'll end up with a DC voltage with much less ripple :)
The sources would isolated until they reached the bridge.
Actually I was interested eliminating two reciprocating cylinders & crankshaft by piping two "liquid pistons" through a check valve bridge to power a turbine.
I'll search Google for a check valve bridge. It may be something that is only useful in theory.
