Art, something I've always thought could be fun is a GL but with the AG airfoils used on Mark Drela's Allegro Lite. It's still all balsa that way and the builder could opt for Mark's hella strong carbon spar buildup or go for an easier spruce spar "high start and light winching" wing to skip the advanced composite aspect.
But at that point I sort of figure that with the extra cruise speed this would all give that I might as well oval shape the fuselage with a nice upper nose block and triangle stock in the corners to allow shaping. And then make the fuselage more skinny to hold the modern gear... and on... and on.... and suddenly it doesn't look at all like a GL anymore.
.... I'm weak that way when it comes to "improvements"
