You might be extremely surprised to learn that Jets models of F16 and F104 fly actually very well with the scale airfoil.....And they have much less wing and much more speed than an airliner !

I would say go for it ! Make a mok model out of foam, and try it on a slope or towed, before doing the real thing, to see how it fly and verify the CG. An airliner is a very fat sailplane......So the mok model should have a nice glide. Once you get it to fly OK, build the final model with the exact same CG, and you should be safe.
