Paul I think your thought process is right on, however the Kitfox is primarily a STOL design, it is dirty and draggy so going to all that effort to shorten a wing to gain speed seems to me like you will be going against the purpose of the design to gain a few knots at the expense of STOL and climb performance.
For me once I put the wing extensions on they have never come off. I can tell the difference in STOL performance, climb, cruise, and slower roll rate. The longer wing makes more sense for the design. An RV would be a much better design if you want speed, but it's all about experimenting. It would be a lot of work, but a fun project.
