How would you suggest fixing the backboxes ontop of the old? I want the
flush fitting ones not the ones with a lip.

Drill holes in the back and fix them with normal socket screws to the old,
then make good with one coat plaster etc round the edges which will make
them rock solid. Normal depth steel boxes for most metal sockets are 35mm,
but 47mm ones are available for cookers etc. And cost very little more
from a wholesaler. Or you could pack to the correct height with hardboard,
bits of plasterboard, etc.
