So long story short- my current WIP is a combination of several ideas I had and started fleshing out- then realized combined it would be pretty cool. How the story stands- it's a post-apocalpytic novel set in Florida. My MC was a cop before the apocalypse. In the previous version his name was Lowell. Then, I decided to combine an unfinished short story about a mercenary in a post-apocalpytic environment into this novel. I kept the MC as a cop, but modeled him after the MC from the short story, and I made Lowell his companion. For the problem- the MC's name is Reed McLane, usually just called McLane. My husband immediately pointed out that was Bruce Willis's characters name from the Die Hard franchise. Originally, this character was a merc, but now he's a cop, and I didn't even think of the connection. I don't want to re-name him, but I'm worried this could be a problem. His being a cop is important because halfway through the book there will be a murder identical to the last homicide he was working on before the apocaplyse , which he will become obsessed with solving. Thoughts?
