so when the Imperial Circles were created in 1500 and 1512, Charles the Bold's state had already broken up.
but what if Charles won the battle of Nancy and thus the Burgundian Wars, and went on to have a son after that, who inherited his entire Duchy / Kingdom.
Charles dreamed of recreating Lothair's empire. With a more powerful, united Burgundy in the HRE, might he push to have Savoy, Provence, and the old Kingdom of Burgundy lands included in the Burgundian Circle, to bring the old Lothairingian / Burgundian lands together? could this have worked do you think?
