The front and rear shafts will be turning in opposite directions, unless you put an "idler" gear in between them.

You could run the shaft from the outrunner to the second (bottom) diff and use the first diff (top) to output to the front and rear diffs.

Why not just eliminate the outrunners dogbone? You could make an end for the motor shaft that plus right into the diff cup. If you "stacked" the diffs one on the other you would clear the rear shaft and still be on the center line of the chassis and not back so far, plus no funky angles to wear out the diff cups.

If I could only draw what I see in my head, then afford to build it, and finaly get to play with it...
