A few questions, 

1. Is there a Black Market for Mech/Frame Parts?
2. Is it possible for me to be a Black Market Part Dealer/Installer?
3. If not, can I be a Mega cooperation?

Oooooo, I like the first and second!

We could drag home relatively intact enemies to dismember and sell for scrap, or repurpose, say, a gun that we don't have but they do, or somesuch.

And being a megacorp is unlikely- we're all mercs. Not organizations.
