Didnt you buy the rear 335i calipers from the junkyard?

If the lug width of the carriers lines up, its relative easy to compensate for offset.
For the 135i performance calipers (the rear ones) the lugs line up exactly (I use that setup). The only thing I had to do to line up for offset was to make some washers on the lathe (in my case 7,6mm thick) and use longer bolts.
The biggest challenge lies in getting the parking brake to work. There are basically 2 ways to do that; make custom brake shoe brackets (welding) or crimp an aluminium ring (made on a lathe) inside the brake disc hat to reduce the diameter from 185 to 160.
And of course adapt the back plate etc, but thats peanuts once you got this far.
