You seemed to have missed the part about the "innovative turbo setup". This is exactly what differentiates the S63 from the N63 today (along with more boost, higher redline, etc.). So the same transformation is possible for the N55 to an S55.
Furthermore, in fact, most M engines have been based upon normal series engine. This was not true of the S65 and S85, but before these it was the norm.
