Do Any of Them Actually Survive Without Biometals?

Who do you think haz the best chances of surviving without their Biometal?

It seems like Grey would technically be better off cuz he's a reploid but his mental fortitude at the beginning doesn't make me feel like he would survive long without a Biometal.

I think Ashe haz the best chances cuz she's experienced with taking on Mavericks by the time all heck breaks loose (as much as I'd like to say Vent/Aile - or specifically Aile cuz she haz a hilarious mouth on her lolzzzzz)
