I'd say change Eclipse into letting Mirage create her own source of light/shadow, like a floating orb of (un-)light similar to her disco ball that stays in place and has a fairly large radius, with dropoff to the boost as well as line of sight between the orb and warframe; tap to create a light, hold to create an un-light. Normal light doesn't affect Eclipse anymore at all, just the light summoned by this new version of Eclipse (and maybe select other warframe abilities).
