... but can one not get true 'large boxes' (rather than a pair of joined boxes)? Will the faceplate in question not fit any of the large 'grid boxes'?

Maybe you can, but the manufactuers don't seem particuarly interested in helping you do so. There is no standard for multi-row boxes and as I said earlier at least among BGs range it seems their "two row euro" plates seem to be taller than their their "two row grid" plates and shorter than their "three row grid" plates. One naturally assumes that if the faceplate size differs, the mounting hole locations will likely also differ. Short of actually buying and measuring boxes there doesn't seem to be any good way to find out if a box and plate that are not specifically sold as compatible are compatible or not.

I think that any electrical wholesaler, and even the likes of Screwfix and Toolstation, are always happy to bring a product 'to the counter' for one to inspect. So if you visited such a place with a tape measure in your pocket .....

No response and still the same.

Unfortunately BG don't give screw hole locations for their boxes or plates, but the overall height of the plate is.

single row - 86mm
Dual-row euro - 186mm
Dual-row combination 13A/Euro - 186mm
Dual-row grid - 147mm
Triple-row grid - 207mm

We know the horizontal spacing - that's the same as any 2-gang item, so a drawing could be easily scaled to find out the vertical spacings.

Or even with the faceplate you want to fit.

Although if you're not using MK there seems little incentive to not just buy the one the maker offers.....

I think that if you have a real need to do many is possibly design your own after first taking a sample of at least say 10 back boxes and a few common accessories of sockets and switches etc of you favourite choices and measure say using a digital caliper then say producing you a few of your own for stock.
But unless you are going to be using more than just an odd one every now and then it is a bit too much of a hassle, the "bodges" I mentioned have some merit as an aid for the odd occasion
