There's one deep hole in your theory.

Ruby and Yang never made any mention of Sister Summer. Yet, they mention their parents all the time.

Ruby may have looked up to Summer in some way. If she was Ruby's sister, then she may have been the reason Ruby decided to be a Huntress. That doesn't seem the case though. Ruby credits her parents as the reason she became a Huntress. >_>
