Yes, it will work. You need to be able to form Al sheet or CF sheets, whatever. I would be tempted to try foam crosspieces in the non-bearing parts and something stronger where the side pieces will join.

Remember, NACA was formed during the jet age. You will want profiles that are designed for slower speeds -- they may have such but that was not NACA's focus... NACA evolved from a C (committee) into an S (Space Agency) - NASA.

Find some of the English translations of dear ol' Prof. Kamm - they amy have some nicer profiles for you, if the NACA stuff is all too high speed.

Have Fun!
