I have no qualms of the F8X using an engine based on the N55 so long as there is significant differentiation and development to make it special as the S54 was.

We all know that previous M GmbH engines were based on BMW AG engine, and they were very good. But at that time the engines were naturally aspirated, so to get more power, significant differences were made. Another thing is, before there wer no thoughts of reducing costs, but now, anything even being better, but costing more will not be made. Now all these ponts put togheter, with FI increasing power is an easy think, and it does not require alot of R&D, thus reducing cost. There only thing where something is invested in, is realiablity. After the 1 Series M E82, that just has a remapped ECU, larger oil cooler and oil catch can, all these thing that could be done by the aftermarket, most are afraid BMW will do the same for the next M engines. With the S63 found in the M5 it is not the case, but in the M3, a good engine is of bigger importance. An M car must be a whole package, chassis and drivetrain, not only drivetrain like the M6 E63, or only chassis like the 1M E82.
