Why not do the same in SoD? Move the restrictions from the Rules into the DATA folder?
I've already written about it and provided a link to an archive of additional files created for a specific set of rules. It includes restrictions on lava creatures, reduced transportation magic, and bans on mapmakers and healing forts, etc.
This patch works perfectly for the tournament that's currently running, and there are no complaints that it's not a "pure" SoD. It's just that some people probably don't want to create a separate patch for each tournament, although some aspects are suitable for all tournaments (e.g., the captain's hat :)).
P.S. You can also change the reward in cans... this is visible in the link above.
