Can't offer an ideal solution,
but
perhaps you could make a socket trailing lead.
You could possibly get a 5 amp plug, connect some three core flex to one end, and n amount of surface 5 amp sockets mounted on a piece of wood to the other end.
You would need to use the tougher pvc pattress boxes, as these will accept a plastic 20 mm flex gland - to prevent the flex from coming out of the box.
Face plates could be metal as more robust. MUST be earthed.
Absolute bodge I suppose, but may solve the problem.
