That sounds great honestly. Zoro would utilize Orochi's fruit better than Orochi himself would. And Asura with 10 swords.
It would be so cool to see Oda draw that. Imagine CoC leaking off 10 blades at once?
Since I think there's a good chance that Toki is actually Zoro's mother, though, just because it would be OP, the Time Fruit.
Being able to manipulate the flow of time with swordplay would be cool, and I think Oda would do some fun things with that.
I want Zoro to remain fruitless, but, there are some fun possibilities if he got one.
