Tried that and it sort of worked however rim is not really an oval so it was not easy to fix. Then it was a rear rim so i had to tune one side 120kgf and other 70kgf and there problem oval reappear again.
Also i was not able to dish rim without having few spokes tension set to 160kgf i guess its bent too much and best to scrap it.
