MAP 65 adaptive polarity?

Hello all,  I am considering the purchase of a
Flex-6700.  Now that you have DAX-IQ, is it possible to run a pair of
coherent two meter (144 MHz) slices, each connected to their own antenna (one
vertical and one horizontal polarity), and output both their IQ channels to a
program like MAP65 to achieve adaptive polarity reception?  Easy choice of
either of the two antennas for transmit would be a bonus.

Today, you can have two 2m receivers tuned to the same frequency and they will be synchronous, but not coherent.  In other words, the two channels will provide a constant phase separation between the two outputs that will be random, but constant and stable after each tune.  Changing this to a coherent tune has always been in our playbook and not hard to do -- the chief challenge is how to represent that you want this from the GUI.  We have also had this request from the HF side.

Can MAP-65 handle two synchronous channels that are not coherent or is this something we need to do sooner?
