Modifying the rudder is something that needs to be done (at least planned and designed) by a pro. Serious balance issues (either over or under balanced) can lead to real problems managing the helm afterwards.
The Maple Leafs have a fair sized skeg, with the rudder extending beyond it with a balancing area ahead of the stock. Likely the K/C version of the rudder is on the shallow side.
To add area to the aft end could create a real bear to deal with and plenty of loading on the steering system. Going deeper will negate the draft advantage of the K/C arrangement (and the rudder would be particularly vulnerable)
This might be a tough problem to address, if indeed it's a real problem on these boats...
