Sorting ribs by weight puts the heavier ribs in the center of the wing if constant chord, but even when tapered, you can balance a wing with careful selection of which panel each pair of ribs go to. Same with all the other pieces that go in the wing.
Common practice for those of us who build our own stuff and pay attention to things such as weight distribution. That's how one may keep his wing and stab panels either exactly the same or within a gram or two for the "typical" 10 pound airplane
CL stunt pilots/builders/designers don't even think about this issue any more. It is done as a matter of course. They know more than anyone how a plane feels in the air. Heck they are connected to it
To the OP....are you confused yet with the answers to your truly simple question? If you are the experimental type, why not do the simplest thing first? Bolt on the weight, get the cg where it needs to be and fly the crate 50 flights. Then do some of the lightening suggestions several of us suggested, and fly the crate another 50 flights. Then report here
