AW4 help

So I have decided to go 2wd with my build. I have a 4wd aw4, and I know to convert it to a 2wd trans I need a tailhousing AND a 2wd output shaft. However this makes the conversion unrealistic. I want to use my 4wd trans without a tcase. Im wondering if I can use a yoke on the aw4 output shaft. and just get a custom length driveshaft to make it all work together.
Basically I want to use the trans I have without switching the output shaft.

Why not run your existing AW4 tranny with existing transfer case and just remove the front driveshaft?

drag, rotating weight, and overall weight. the entire point is for weight loss.

I am aware of the easy, and obvious solutions. I have a strong known good, and low mileage 4wd aw4. In addition to the fact that I believe, (not certain) that the 4wd has a much stronger output shaft. short 23 spline vs long 21 spline.

All 1991+ 4WD AW4 output shafts are 23 spline since they mate to a transfer case.
That does not matter though. The 2WD AW4 mates to a drive shaft which requires 27 splines. All 2WD AW4 transmissions have a 27 spline output shaft for the drive shaft.
