GAMO Coyote and Phox PCP's actions & stocks interchangeable ?

[hendrickotto]

Why is the Phox (or Urban, or Chacal - all are indentical but for the marketing name) only offered in .22 I wondered.
Could the shorter Phox stock take the somewhat longer Coyote action and would the Phox action fit into a Coyote beech and/or synthetic stock ? Latter one, by the looks of, it might be too long to take the Phox action because of the barrel band assembly getting into the way of the fore end.
Anyone ever tried these swaps ?

Reason ? Getting a .177 caliber Phox by buying a Coyote with Phox spare stock might do the trick......
Plus of course in order to compare handling I would like to try it the other way around.

Many thanks,

Hendrick
