My first balsa build was a scratch build of the Gym Swallow

It was much easier to build than I thought and it flies nicely. I even built a sport wing with ailerons so I could learn to fly full house. It is still very gentle and is great for small areas. It is not at all aerobatic but it looks like you have plenty of those hot planes already. If you want to slow the pace and build something out of parts you fabricate, you might enjoy it. It is very satisfying to build something from a few sheets of balsa, an arrow shaft (for the fuse), some piano wire, and some Reynolds wrap (although I used Solite for the wing and horiz stab).
