I agree with you. I didn't know that part is made by an NI owned company. I know with beecube and ettus, other companies that NI acquired, they slowly integrated them to be supported by LV FPGA.
I wonder if adding LV FPGA support would add to the cost of the card; personally I would not be surprised since LV FPGA as a dev tool is lower in cost than other high level FPGA tools that output VHDL; with LV FPGA they seem to recoup the cost via hardware sales.
If the pin configurations of the two boards are the same, you may be able to send that bitfile (less the header I think) to the PYNQ board. Would be interesting to see what you come up with.
PS I kudoed your lv fpga ideas; really good ones!
