Copyright Law

Can i sell iconic images of celebrities with their heads painted over on my online store?Is this a copyright violation or legal appropriation?

- I want to create a series of paintings using the bodies of celebrities and paint over their heads with random animals - The bodies of celebrities will be the same, but their heads will be completely different and so will the backgrounds. Imagine an iconic Marilyn Monroe photo with your own head replacing hers. Regardless if you are male or female - Is this copyright infringement? - If yes, Is there a way to get around the copyright infringement? - I want to mostly sell in the US, UK and AUSTRALIA I really appreciate your assistance here, means a lot!
