A mild upgrade could be using the longer carriers from the D2 armoured car, and either trying to source cheaper D2 armoured car discs or some other discs of similar size that will fit the D2. The D2 armoured car rear calipers are the same as other D2s so no new calipers needed.
armoured carrier part: 4D0615425D
discs are 310mm by 22mm

I wanted to go for the S4 B7 set up. Just a thought, instead of drilling out the D2, could inserts be used in the B7 carrier so they will accept the smaller size D2 bolts?
Just in case you ever want to go back to the standard brake set up.
