2 MOSFET H-bridges, 2 loads, 1 common side: possible?

Hi, for a specific project I need to join one side of the (different, +/-100mA) loads of two H-bridges together (lug P1 and lug P2).

For that purpose I thought of using one side of the bridge as a common, and drive the other side by the same gate inputs but on 2 separate bridge sections.

See attached drawing: a standard set of 2 H-bridges, and my idea of getting one side of the two different loads on a common wire (lug P3).

Suggestions, comments, remarks? Anything is welcome,
thanks, Erik

Solved: the two loads A and B are being placed in parallel in one bridge, current measurements per load can still be done. That was an instance of tunnelvision :facepalm:.
