I started a project over a year ago to try balanced lug sails on my CS 20. I made some 16' aluminum masts and sails out of polytarp. Then I herniated a disk so that got put on hold. I should be able to finish that project this spring. As usual I got a bit carried away and ended up with 90 sq ft sails. I put in two deep reefs.
With the yard I expect about the same weight aloft. When I put a reef in the yard will be lower which may make a slight difference in how much weight is swinging around aloft.
I look forward to seeing how, or if, it works out.
If I like it I may sew some dacron sails to replace the polytarp. Time will tell.
As stated by others a CS can handle some pretty good wind. I did manage to turn my CS 20 over once though. Operator error on a local reservoir. After that I converted to sail track with a couple of reef points in each sail.
In the 2011 Texas 200 we were hitting 10 mph occasionally crossing Corpus Christy Bay with double reefs in the main and mizzen. The sails as designed work great. But I guess I just need to play with y boat. The advice to go with the as designed rig is good advice. It is well proven. It is possible to experiment after the fact with cheap materials such as polytarp.
Enjoy your adventure.
