No. No. And no.
First off, there's nothing wrong with Samus being a pretty and sexualized girl. You play 100% of the game in her suit, so doesn't matter how big are her boobs or how pretty is her face. In fact, it shows that also pretty people is capable of awesome things. Your proposal for the zero suit is just disgusting. Horrible. Terrible. Words can't say how bad is the idea.
Secondly, Metroid doesn't need a reboot. What Metroid needs is to be honest and fix everything wrong with Other M because there's a lot of potential in the mix of 3D and 2D series. They can start with an isolated game with a new refined mechanics of Other M. No orders, no Adam, no NPC's. Just Samus exploring a complete planet, Pirate's Stronghold.
The only thing I agree is that should be scary again. Love u Prime 2.
