I will have tighter NDS spokes come hell or high water!
Putting lighter spokes on the NDS is also an option that I have tried and works well. The original 13g stainless steel spokes were too rigid for the lighter tension on the non drive side. I fitted cheap galvanized 14g on the nds side only which were far more flexible and bedded in nicely at the lower tension.

All my builds use 14g spokes, my first and only bought motor wheel I rebuilt with new spokes as I had issues with the build using 13g ones.

When you add so much stretch to the rear dropouts, you might find that the rear wheel might need to be "dished". Spacers at the brake disk can make this even worse, so be prepared for geometry adjustments.

All you need to do is put M6 washers between the caliper and the frame to make it line up with the disc. When you spring the frame out, the disc mounting becomes a little bit out of line, so you might need some thin and thick washers and juggle them around until you get perfect alignment. I have a jar of M6 washers, and they're all different thicknesses, so no problem for me. Normally washer thickness doesn't matter, so have a look around and see what else uses them and swap some around to see if you can get the right thickness you need.

Yes I originally planned to set the caliper 5mm inwards, but then the (BB7) caliper would be touching the j-bends of the spokes, so I can't get away with it.

I could get a thinner caliper, but it's more faffing than just putting the disc rotor spacers on.

I am adding 5mm of spacers to the inside of the NDS dropout that will send the rim 5mm that way > then tightening the NDS spokes to get the rim 5mm that way <

5 -5 = 0 :p

My spokes are 2.5mm so I don't want uneven tension if I can fix it and, along with disc rotor spacers, this should fix it.
