Do you plan a magic system which enables the character to manipulate the four elements with their will? I mean not so bounded, like Allomancy with Pushing or Pulling but shaping/summoning the elements according to the wishes of the person. I ask this, because in the whole fantasy genre I rarely find something like this (except: Arc Magica RPG), so I had to develop it myself at home. But from the authors I know you are the person who has the creativity to do this without doubt.

Maybe, but there are a few problems here. For one, "Four elements" magic has been done over and over in books and video games, so it feels hard to make fresh. And in what you describe, it sounds like the characters would be very powerful, which makes for a challenging story to write.
