Beagle there are two answers to that well founded question..
1. NO
and
2. Check the Boeing Tanker website, does it show any footage of real aircraft refuelling from wing pods or centreline hose and drogue IAW with the KC-X solicitation?? ( for guidance see answer 1.)
However in their defence the USAF have asked specifically for a limited capability Tanker, so thats why the 767 is a good fit.
