Why not? A relatively inexpensive 510mm F4.5-ish AF lens for Pentax. As I recall, the Arsat retails about GBP699 new. As I have a nice condition used one lying around...................why not? Even a manual diaphragm version would be fine by me. The AF will still work ok. Frankly I am surprised that Illinois Bill has not seized on this already.
