Sorry, but that is not what "convention" means exactly in mathematics. It means that you might have defined it in some different way, but you do define it in exactly this way, because that is what on average saves everyone the most work in trying to express or calculate something with it. Please just stay with the "convention" and you will be clearly understood and you will be fine.
