Yes, I think so.   Basically, we need three things.

 (1) Porting board specific things: clock, LED, etc.
     This part would be easy, when you have a specification.

 (2) Porting Chopstx (the thread library) to Cortex-M4.
     This part would not be that hard, as you describe.

 (3) Porting MCU specific things: USB controller and ADC converter
     drivers.
     This part takes time to understand the MCU.

Yes, I agree.  Currently, Gnuk depends on a single semiconductor
vendor's supply.  That's not good thing.
