Why not just modify the /rear/ yoke to add a pulley in it? Then, you could mount your motor right on the rear differential. To drive on just motor, put the transmission in neutral(and/or add a transfer case and put that in neutral if the drag was too much).
When driving on the engine, you could use the motor in a regen/charging configuration as long as you were moving; great for recharging when highway cruising.
Another benefit to this would be not having the weight of the 4x4 system.

I contemplated that, but one of my long-term goals was to convert my van to 4x4 once I found a junked 4x econoline in the southwest. By doing the hybrid conversion on the front, i get to keep my existing setup plus get the benefit of cruising on electricity with the front. I can still do the regenerative charging with the front if I wanted. Also, if I went up into the mountains, then I'd have 3 wheel drive.

Then, at a different time(or the same time) you could add the front diff and front driveline... perfect 4x4 + hybrid.
Also, one thing I'd be concerned about with regards to using the 4x4 at the front all the time is that we have U-joints instead of CV joints. Any angle other than straight creates a varying speed in the shafts going into the differential, and you are going to be getting some vibration when going down the highway, and it'll feel really weird going around corners. It works... but it's kind of odd. There's a good reason that AWD vehicles(and lighter-duty trucks) use CV joints instead for the axle shafts in the front.
Anyway, just a thought.
