I have seen an example of an electrician fixing a metal box to an
existing studded wall by glueing a suitable spacer piece to the other PB
back then screwing the box to the spacer.

Here, I generally use battens either side of the metal box fixed through
the plasterboard with brass screws. Then just fill the heads. Saves
messing around waiting for glue to dry. Of course if working in an already
decorated room, glue may be required. You often have to drill holes in
some makes of boxes too for the screws between that and the battens.

Of course for DIY, it's only my time. I doubt a pro wants the fiddle.
