RAISING, not lowering, RAISING the carrier bearing

ive given a lot of thought to how to rectify the angles going on in my drive shaft. what ive come up with is an idea that i havent really heard anyone else mention. my transfer case angle is 3.5degrees. not huge, the Carrier bearing angle is
3.4degrees farther down, so total 6.9degrees compared with the TC output. the pinion angle is
6.8degrees compared to the rear shaft and .1degrees compared to the TC.

looks like this:


The truck has some vibrations and minor shudders. Id like to fix that with a double cardan from Tom Woods. But instead of the whole enchilada, I would like to do a replacement for the rear shaft. Ive read too many issues with the single shaft and appreciate the weight savings of the two piece. so, Double cardan at CB in order to handle the increased angle. It would look like this:



If i raise the CB 1" it would set up a 1degree angle at the TC, a 4-4.5degree angle at the CB and I would shim the axle up 6degrees to create about a 1degree pinion angle.

The diagrams above are made of paper strips cut to scale in centimeters. the angles were made with a protractor. It should present a close approximation to what will occur if I take all these steps.

I guess my question is this:
has anyone else done this? How did they do it? I could cut away small sections of the CB cross-member-mount to allow the current bearing to be mounted on top of it instead of under it. Or i could replace it completely with a bearing that holds the shaft higher. either way, it needs to be elevated 1"

Thoughts? Considerations Im missing?

 

Subbed for more info. my truck is lowered and could benefit from lifting the CB up as well. Curious to see what comes of this

 

Maybe I misunderstand what causes the vibrations. However, I don't think this would solve the issue. I believe that the vibrations are caused because u-joints are not a constant velocity joint. The joint actually rotates faster on the obtuse angle side of the shaft than it does on the acute angle side. So it has to do with joints on either side of the CB rotating at different speeds in addition to the joint closest to the rear diff.

I dunno, maybe I'm wrong?
