I don't think it'll take that much effort to select modules or excise options. In many cases, I assume you'll have to make a decision about what to include in your game.
For example, under the Health and Long Rest dial, I'd expect to see something like the following:
Heroic <--> Balanced <--> Gritty (Choose one):
A. Heroic: Regain all HP and HD after a long rest.
B. Balanced: Regain all HD after a long rest (you may spend them to regain HP).
C. Gritty: Regain 1 HD per long rest (you may spend it to regain HP).
Sidebar--> Explains each option on the dial and how to place the dial in between options, or even lower or higher.
Now obviously, you will have to excise some of these, since it would be hard to use all three simultaneously. Also, note that all three healing systems are default, core systems, so noones preferences are out of the spotlight, so to speak (new players are introduced to all three simultaneously, etc.) Rinse and repeat with other aspects of your game, such as ability scores and races. The rarity system of the races already points to this:
A. Include Rare, Uncommon, and Common Races
B. Include Uncommon and Common Races
C. Include only Common Races
If the "packages" are properly aligned, it might even be so easy for you to tell your players, "We're going for all C packages for this campaign."
