I think Star Fox 64 did it right (Destiny)

:p

There were some triggers in most levels that, if you managed to hit all, caused the on-rails level to go somewhere else and most likely fight an entirely different boss (or even skip it).

I think that could be useful in Strikes. Hell, it even was in place already with the Black Spindle mission. Imagine if you will, a Strike that offer you an entirely different boss or boss encounter if you manage to trigger a few key events throughout it. Or a Strike that ends in a The Maw-like Sparrow segment if you kill the boss in one of the chase scenes (as opposed to the final boss fight). I for one, would very much like it.
