Help with completing a champion idea

So I was rvising for exams when this champion idea came to me the main theme is a champion that can change autoatacks throu changing his weapon So for his Q i thout of a syth (since i think league need one on a champion) when he activate Q his weapon changes to a syth and his auto becaume melee and aoe and he get a passive for a duration after the activation giving him bonuses that fit to his syth like life steal or atack speed or every 3rd auto he striks in a circle around him also when activated he pulles enemy toward him abit so he uses Q pull enemys and get a buff for a duration then he just auto normally for W i thout of gunns I didn't think of the activation ability like the pull on his Q but it can be a skill shot in a line and gets a buff that fits his guns play style ofc he gets range for E i thout of a weapon that looks like akalie's weapon abit but attached to a chain it has medum range (not as long as his gun form) when activated he lunches a skillshot in a line that stuns the first enemy hit and he get pulled to them put doesn't pull the enemy stun and when cast on a wall he can leap to it and if it's thin enauph he can leap behind the wall For ult i haven't thout of it well but it can boost all the efects of his abilities for a duration Also i haven't thout of a passive Auto attack damage is not the same at all form so you won't get to play only using one auto attack form for the rest of the game so maybe damage reduction on a form and damage buff on another one But i layed like a theme or a base idea and i'd like coments to complete what is missing or changes and make it fan made Just few things i really want is the syth because i think it's a cool weapon (that is not used properlly by fiddelsticks xD) and beside using it to throw bananas i think it should be used to slash enemys in meele attacks and i'd love white hair and red eyes _
