Unfortunately, the front door opens past the masterbox IYSWIM, so the larger
offstand of the faceplate splitter is likely to be an issue.

Is the existing socket mounted on a pattress? If so could replace it
with a ordinary metal back box and sink it into the wall to gain more
"depth".

Is there a neater faceplate which will allow me to take A & B into the loft
and fit a second master box up there?

Is the master socket used? If not, leave it alone, take you feed
upstairs and use something like:

ADSL-FFP85D on http://www.solwise.co.uk/adsl_splitters.htm

This will then let you take both filtered and unfiltered connections to
other sockets from there.

I don't want to wire direct to the incomers as this ist verboten

No need, and not desireable anyway.
