surface mount cables that don't appear to serve any purpose looks very naff
Short answer Yes.
Of course cables should be mechanically protected so trunking or conduit if not buried more than 50mm.
although I anticipate there will be 4 or 4 circuits so will be a lot of them, unless they are available for wider/numerous cables?
why don't you put them in surface mount steel, then box around the steel with plasterboard
(steel because it would be a concealed cable and not in a safe zone)
