Boeing 707 and related (720, C-135 etc.)

The wings from the 1/72 Lockheed Martin P-3C do fit onto the C-97 so the wings from a Lockheed Super Constellation. I have tried converting the C-97 Stratofreighter into a Rolls-Royce Tyne turboprop version.
I did have a idea to do a Super Guppy using a plastic milk bottle.
