If this became a thing, what would you expect from it? And which of the following would you prefer?
>Adaptation of the Zero Mission manga, with a few changes
>A completely new origin story which would act as new canon for the future games in the series
>Not an origin story at all, but a story set well into samus's bounty hunter career, possibly after fusion
