Well, Susanoo is a chakra construct according to some people. I don't know if it's true or not. But making Susanoo use Rasengan would require an immense amount of control and a longer period of time if attempted without the Six Paths Power.

It won't be like Naruto, summoning an instant Rasengan and striking.
