HumansCanWinElves has the right general idea. However, I personally think having a parameter just to toggle use of alt parameters is going to be more confusing than not for casual/new editors. Even more so since it will appear just like any other text input; there is no true/false input field (i.e. radio buttons or check boxes) for template parameters.
