SDR latency is a little loner than conventional ,  But , as is ,  its not possible  for  say
a two  way connection , using , Flex SDR<> Flex SDR  and the  Chat module 
probably a case of  unexpected consequence ..

Yes, with Dwell Trimode 4.5 seconds it would be possible to do a simple change to VARA HF to connect two SDRs: SDR<->SDR.   Although the latency in this case would be about 1 second due to both VAC. 
 
But Winlink demanded 4 seconds maximum Dwell, so only is possible  SDR<->Conventional  or  Conventional <->SDR.   
 
In VARA FM or VARA SAT is possible SDR<->SDR because there is no DWELL time requirements.
