Splicing Ballscrews

I understand that you can splice ACME screws by facing the cut ends,
center drilling, reaming, align the threads and join with a dowel pin
and loctite. The procedure for linear ways is the same. Can you do
this with ball screws? I have two identical ground 1.5 inch 48 inch
long ballscrews and zero backlash nuts that I would like to make a
single 96" for the long axis on a router.

Has anyone done this? I would hate to destroy two good ballscrews.
