I don't know if that engine is too big/heavy for the M3/M4, but I can only drool thinking about how that car would have truly been the "hot 3er" that we all wanted.
The perfect turbo engine for the M3/M4 would be an short stroke 4.0ltr.V8TT based on the 4.4ltr.V8TT S63Tü from the M5 ... look at the bore/stroke ratio of the S55 and imagine this for an S63Tü derivate and with the same weight saving measures developed for the S55.

The S63Tü is a little bit heavy (230kg) for the lightweight M3/M4 but with the neasures taken at the S55, I am sure it would be possible to bring the weight down to the S65 weight or at least to 210kg.
