I understand your request on this as i have been wondering the same myself recently, but i doubt it will work.
since no diecast mfr. has a 1/200 pre-62 series DC-8 mould as of yet except herpa but that mold stinks. i keep seeing a vintage National Airline 1/144 decal set on e-bay that i am interested in and 1/200 plastic DC-8 50-61s kits from time to time, but no 1/144 scale models to match them with!
