[Netflix MCU] Where does Nicolas Cage get his name from?

In the real world, Nicolas Coppola goes by the stage name Nicolas Cage in tribute towards Luke Cage, a fictional comic book character. 

In the Netflix Marvel world, Luke Cage is a real person, who first appeared in the public eye as a hero of Harlem about thirty years after Nicolas Cage became famous as an actor. Where did MCU Nick get his name from?

His name was either always Nick Cage, or he picked the name for unrelated reasons.  Perhaps a different obscure comic book character.  Or Johnny Cage, from Mortal Kombat (who must have been a pre-existing character for Nick Cage to have a career in the 80s with that name, since the video game came out in the 90s).

Just like Nick Fury in the MCU doesn't look like the guy who played Mace Windu.

We're looking at an example of Sylvester Stallone playing the Terminator here.
