Sure E92 had a more special engine, but that was helped by the fact that the M3 GTR had a tuned version of this engine for racing, and it existed in V10 format already. Easy to lop off 2 cylinders. If the S65 didn't have such a short stroke (poor for turbocharging) they could again lop off another 2 cylinders to make V6 Turbo.
As for more options turbo charging a V engine, that is rubbish, an inline engine is much easier to plumb.

I don't know if I agree. The S50 and S54 didn't really share anything with the standard motors except for the configuration.
No matter how hard you try, you will never get an S54 head to mate with an M5x block for example.
