As a rule of thumb, Royal line of prosession generally don't apply to family businesses. Rarely do you have family businesses of that scale be "this kid is the heir, in control of everything. Thought shit other kids." There may be a level of importance placed in certain members over others, but generally a corporation can have multiple family heirs, each substantially filling a certain position or rank.

Putting that aside, I'm of the theory that Season characters aren't necessarily related to one another, but instead each related to one of the rwby girls. Summer and Winter already fulfill this criteria which leaves Fall and Spring(or which ever variant the crew chooses to use).

Cinder's the biggest hurdle as it's questionable at best if she's related to Yang and outright confirmed that she and Blake aren't related in the slightest.
