I think so, even though I have to switch from Pencil Pro to the USB-C Pencil. I also doubt whether it will support features like Stage Manager, Window management, and extended monitor support.
Definitely going to reduce my bag weight. Having a Duo (iPhone + iPad hybrid), I can only carry my Mac in the bag instead of another iPad. When I don't have my Mac, I can still just bring a keyboard and use it with my Duo for some tasks. The only thing I wonder is if the Duo supports mice and trackpads without the need for AssistiveTouch as the current iPhones do. If so, it's gonna be a great mini desktop computer I can just carry in my pocket.
