In addition to seriously increasing leeway while close hauled, you also risk seriously messing up the balance of the boat. You are taking lateral area away from the keels, and moving it back to the rudder
. This will have the effect of moving the center of lateral resistance aft pretty dramatically, which will increase weather helm
Also, don't forget, you will need to keep the rudders "balanced" and add area to the front and back of them. If you just add area to the trailing edge of the rudders, you will GREATLY increase steering
A boat is a "system" and chopping it up can have serious consequences, that might not be obvious beforehand to the "novice" navel architect.
But, again, in your charter business you might not care because I suspect you don't spend a lot of time sailing hard on the wind
If the resale value isn't important, then it's your boat!
