Never tried it myself, but if it’s popular enough that probably won’t matter. The nice thing about a mod is that you can always mod the mod. The kind of players who are willing to try a modification are the sort who are probably willing to accept minor tweaks to that mod later on, if it still ends up tilting to one side over the other.
I think the hardest thing to do, is simply to persuade enough people that its worth their time to try something new, or something that departs from OOB with the aim of making the game more fun. Usually the problem is an overabundance of mods or HRs, such that its hard to popularize any one mod or rules change over another. Thankfully the people in my playgroup have been pretty open to house rules or set up changes, but even then they sometimes suffer from an HR overload. The desire for consistency sometimes trumps other considerations.
I still wish that alternate scenarios would receive some official support. It wouldn’t be very hard to do. All it’d require is a new pdf set up chart that players could download, or an addendum to the manual/faq providing some different official alternatives.
Unfortunately in the cases where this is done, it’s usually meant as a fix to some oversight or some misprint for the boxed game, rather than as an optional alternate game.
Even the most popular kind of alternate scenerio, the bid game, has never been addressed officially. It’s kind of a bummer, because absent some official guidence/sanction from the designers, the player base tends to splinter over these things, with lots of different ideas, none of which ever seem to gain enough traction to provide a long term solution to perceived imbalances with the OOB game.
