And hiring competent writers.

All "the baby" jokes aside this approach looks genuinely interesting for both the Metroid franchise and a more palatable personality for Samus.
Perhaps a post Fusion game where Samus finds and bonds with another metroid hatchling. Then has to protect it from the then villainized Galactic Federation which is looking to weaponized the species (again) just like the Space Pirates before.
The biggest hurtle would probably be Nintendo employing an appropriate studio and granting the right amount of creative freedom.
