After you make P2d or after you make Mp2 2d you can make(Suggestion)Metroid Zero Mission 3d.It would be cool.MZM3D 
no.
Metroid Zero Mission is built for 2d not 3d no one will work on that and plus it a remake of the first metroid(1985). Now I wish they have Metroid 2 and Super Metroid for the GBA.
There’s already a team working on a M1 3d, which has a few MZM features but is mostly based on the original. Also, no. Just no.
