Thanks for the reply Mark. The inverse optocoupler design is not really compatible with the standard FET drives from any existing controller boards without another interface board.
If I am going to present a design, I am happy to be responsible and to help others as much as I am able. There is a risk that by trying to interface to existing methodology it might also create issues that I dont really want to contend with. The optocouplers are integral to my power boards and have buffers attached all with very short PCB tracks.
Here is a block diagram of the concept: The top unit has 16 FETs in total, the bottom configuration would have 32 FETs in total.
If at first you dont succeed, I suggest you avoid sky diving.... Cheers Mike
