Rear rotor swap smaller

The m850 has the odd sizing in the rear, at 398x28 while the M cars using 380x28. I purchased custom floating rotors but it turns out they won't be about to make the rear 398 sizing as requested. I either get a refund or pursue putting the M sized 380mm rotors in. I'm ok with this as it'll help further reduce a good amount of rotating weight but I cannot understand if they will fit in current form. The M8 and m850 both have the same rear caliper, same pad, same caliper carrier but 18mm delta diameter.

Does anyone know if there's a way to make this work?
