I'm confused do you mean Mugetsu as in the form he had with long black hair or the form where Ichigo just came out of Dangai.
A lot of people get this confused so I'm just wondering.
If you mean the long black hair form, then...no I'd rather not I mean that move gets rid of Ichigo's Shinigami powers, perhaps if he could use it without losing his powers I'd like to see it.
I would like to see however a dual wield Dangai Ichigo form.
