Question - how to start the game again, but with already open content in the game? (Batman: Arkham Origins)

Hello. In general, I wanted to replay the game again, but I'm afraid that the content that I have already opened will be closed on a new one, and I will be too lazy to open it, so the question is whether it is possible to start a new game and even with all the already open content, etc. with costumes, game art and character trophies?

Spoilerp.s - I'm sorry for asking so many questions, but they worry me now, so I need answers to them
