Can we republish our application with new name, delete in-game item and change the application paid?

We
have a problem with our application Storm Hockey VR. When we published
the application we made a mistake - the application was published for
free and the only in-game item cost $0.01 for a long time because we
forgot to change the test price to release price.
Therefore we want to republish the application with new name, delete in-game item and set the application paid.
Can we do that? Could you offer some solutions of our problem if we cannot?

Thanks.
