If this is a problem I think I can see two possible solutions. Firstly, use my small round file to remove one lot of threads, probably from the 'scope rings, or I was wondering if an appropriate spring washer would take up the slack in the mounting face.
Any advice appreciated.

Yes, it can be done but in order to align the ring at 90º to the plate there is likely to be a gap. Measure this gap with a feeler gauge and use a washer slightly thicker than the gap. This saves altering either the ring or the plate.
Otherwise I would be inclined to drill the hole in the cheaper part to let your bolt pass unhindered by the existing thread.
