That sounds like so not working on the street!

Extra carrier bearings = more driveline friction; extra u-joints = more driveline friction; extra carrier bearings and u-joints AND slip joints = more driveline mass.

I went the other direction on a '74 Chev pickup. It had a 2-pc shaft, I replaced the u-joints and carrier bearing only to have vibration afterwards. Just by dumb luck I came across a 1-piece direct replacement about that time. Put it in there, things got smooth, and I never looked back.
