The more I look at the mcHF, the more impressed I become. Once I get
caught up with my current projects I'll seriously consider getting one.
The FreeDV code and more importantly Codec2 are indeed open source. I
don't know how much room there is in the K3/KX3/KX2 firmware to add
something like this but if possible, it would be quite useful in getting
more FreeDV activity going. in the meantime, I'll make up some cables
to connect my KX2 to my SM1000 and give it a try.

As I understand it the FreeDV code is open source so Elecraft would
not need to reinvent the wheel.

Strangely the mcHF website doesn't seem to mention it but that's great.

The mcHF does indeed have FreeDV built in RX and TX (I'm looking
right at it)
I'm running ver 1.5.7 of the firmware (Ia little old as I have not
updated it recently)

While the mcHF has some digital audio circuitry, I don't believe it
provides a digital voice mode.
FreeDV is a very narrow-band (1.1 kHz) digital voice mode using the
open-source Codec2, developed by VK5DGR. One can run FreeDV without a
computer using the Rowetel SM1000 adapter
(https://www.tindie.com/products/edwin/sm1000-freedv-adpapter/). This
should work nicely with a KX2 or KX3 for portable FreeDV operation. I
haven't tried doing that but it looks fairly straightforward.
