Changing From Tropical To Marine?

[Smells a bit fishy]

Can live rock become alive again once mixed in with live rock, or once it out of water thats it, it can do anything?

So would I be able to get away with having 10kg of dead and 15kg of live?

Im wanting to do that with my new tank but in a large plastic box.
