MultiFlex for Multi Op - any way to avoid delay from PC Audio and MIC?

Using SmartSDR and PC Audio either in LAN or over Smartlink introduces significant delay which makes serious contesting very hard or impossible. I would like to use 6600M for 2 operators in MS setup in one room. I can connect the MIC, PHONES, PTT and KEY for Op A directly to the radio and define that client for Local PTT. That works OK. But OP B is forced to use his PC MIC and Audio for his Smart SDR connection and that makes things problematic.

The obvious issue is that DAX and MIC can not be used at the same time so he has no way to use voice keyer.

But more problematic is the audio delay of ca 1 second or more perhaps that comes into audio and that makes serious operation quite impossible. 

Flex itself and audio from radio also has a small delay which is disturbing but can be lived with.

I am thinking if there is any way to solve this. Would it be possible to take Audio of the Client B also directly from the radio somehow? Can ACC connector be allocated some pins to create "local ptt 2" or MIC/AUDIO inputs/outputs (and PTT/KEY also) for client B? They are in the same room and would very much like to connect to the same radio not through PC (connecting paddle is another problem through PC).

Flex guys, is this theoretically doable?? Currently the vision I had (and I hope you had when designing this) to be able to use MultiFlex in contest is not fulfilled for serious contest stations.
