The fitting kit and instructions for the ceiling-mounted unit show

threaded connection so isn't of much benefit.

I've been unable to find any ceiling-specific fitting kit for it, and
have been unable to find much detail on the plumbing detail of ceiling-
mounted heads. I was wondering about using a steel plate with a pipe
welded through it, tapping it at one end to take a feed from my shower
valve pipework and tapping it at the othersuch that I can pop it
through the ceiling and screw the showerhead pipe onto it. This would
give me a water feed AND take the weight of the showerhead, which is
quite heavy as it's large and well-made.

Does this sound reasonable? Does anyone know of any kits to achieve
this, or do I continue down the DIY route?

It all sounds a bit over complex...

I would have thought sticking a wood batten between a couple of joists,
and arranging the pipe to run horizontally to the batten, and then use
an elbow to pop down through a hole in the batten. The end of the pipe
fitted with suitable fitting to take the shower pipe at about finished
ceiling level, and screwed to the underside of the batten.

Have a look at the way John has provided a mounting for a bar mixer
shower in a stud wall toward the end of this article:

Imaging something like:

but mounted in a ceiling with a single pipe from your mixer valve.
