Okay, I'll have to find it again, but I've got drawings for a four-seat. 2+2. Hunter trainer (the idea was a crew trainer for the TSR-2 as well as a larger "Admiral's barge"). It's still a doable concept and it's on my "to do" list. Of course, the most obvious "whiff" is the CFE's suggestion of a three-foot extension just aft of the forward transport joint to enlarge the fuselage fuel tank. That may get added to my P.1083/P.1109B cross.
