Apparently the mitigator route is what Phantasm used for Cyclops in his Marvel reboot project:

Also keep in mind any extra options for mitigators on "always on" etc that are just temporary disadvantages characters can choose to use: Cyclops can close his eyes, Black Bolt can remain mute, Future Flash can choose to slow down (although that one is probably just "Usually On" for his powers).
