It would be feasible. You'd have to write a new input driver for spectool.

Currently Spectool only supports WiSpy devices. I'm developing a fork to support airview due to requests & people supplying hardware, but since Metageek has been amazing and none of the other vendors have cared, it's going to be separate.

I'm not entirely sure how to handle some things - namely, that spectools implements the chanalyzer protocol since metageek helped develop it, but that's intended for wispy devices.

From a technical standpoint, what you need to do is look at how one of the usb drivers presents data to the callbacks, and fill in similarly.
