@GreatestSin, no it wouldn't (in my opinion). It's not that SUsanoo allows a bigger scale, it's that Sasuke himself scales the jutsu to fit Susanoo. Considering Susanoo is a technique that uses a lot of chakra, it wouldn't make sense if it "allowed" the user to use a larger scaled technique.

@Ultima, The easiest answer to that is that Kishi drew it that way as a representation. But to be honest, I think we're mostly on the same page. It takes more chakra to make Susanoo use a jutsu. My point, however, is that the use of Susanoo doesn't "allow" the use of techniques on a bigger scale. Also, maybe Sasuke's just letting Susanoo do the handseals for him, since he himself in the Susanoo doesn't move during combat usually.

Also, if you could give me an example where Sasuke's Susanoo used handseals before a jutsu? I know Madara did for the meteor technique, but Madara used handseals himself too if I recall. When did Sasuke? I'm not saying it didn't happen, I just don't remember very well lol
