Steve,
I've built CL models in the 1950's and every decade since. There's a thing called kit-bashing. If you wish to build a 3D PATHFINDER - go for it!
It is an excellent design - even the 1/2A feels like a serious, bigger version - so go on ahead! Do an upright or inverted engine, full body version. However, keep the relations between wing and prop rear face, wing and tail the same, or you'll be in an entirely different world. THOSE proportions are what make it a great design - don't go waltzing off in an unknown direction!
Keep us informed?
