Actually I've already given Auxerre back to Burgundy, so my current setup is the same as the above screenshot apart from that.
I haven't looked at the kingdom of Burgundy yet. What do you think needs tweaking with Dauphiné?
Lyon and Forez never were a part of Dauphiné. (or any duchy indeed).
But it lets the viennois the only province left to Dauphiné, which isn't ideal. The only way to workaroud would be redrawing/adding provinces but it should require another type of work which isn't your goal I think.
