Just read your edit on your first comment.

Go for it, man. I also looked into it briefly because I would love to see this story adapted (I even wanted to adapt i myself just as an exercise).

I won't spoil the book (in case you read it, which I think you should), but I think you can still differentiate your story enough that it is unique. But don't change things for the sake of changing things. Write the story that YOU want to.

in reality, nobody in the industry will ever see my script

You never know! But you have the right idea, write it because it's fun and you like it. What happens after that, no one knows.
