That would resolve some issues.
It was tried in recent decades by at least one independent league. It would allow for operation like a big company. If someone is blocked from promotion in New York, that person might be offered advancement in Chicago. That type of thing.
Also, a company would not let one of its locations fail without taking action, which would include an influx of management help from successful operations and transferring people to bolster the "team".
And if that did not turn things around, the location would be closed or relocated.
