The next question was: How can the captive nut be attached to Lego?
If turns out a Lego structure as shown can hold the nut securely. Wrapping duct tape around the nut enlarges it (and is slightly deformable) making it a tight fit and avoiding any play.
I've tried to make all the captive nut attachments out of blue lego.
Having added the captive nuts, bearings, threaded rods and motors to the XY stage it now looks like this:
Note the arrangement motor----captive nut----bearing in both axes.
