Frankly, I'd be fine if a realistic implementation of ARMAT could be implemented even if the exact version we have may or may not have been able to support it, ala Kh-66.
However I would not think it a good idea if a realistic aproximation were not possible, if RAZBAM don't have much of an idea as to the target selection procedure / HUD symbology of the ARMAT in Mirage 2000 type fighters they shouldn't bother.
