I don't know if you were joking, but a k-mount GXR is a contradiction in terms. The k-mount is, by definition, an interchangeable lens system. The GXR is, by definition, an interchangeable lens/sensor module system. There is no way that they would ever make a GXR module that would accept k-mount lenses.
They claim that the reason for the GXR being the way it is, is that the sensor and lens can be a matched set and give better results than an interchangeable lens system can. I don't know if this is true or not, but putting a k-mount on it would mean it was no longer a GXR.
