Yes, i am sure your theory is right, cause look what wookiepedia says:
Satele Shan has been confirmed as a descendant of a main character from Star Wars: Knights of the Old Republic. Due to her surname, many fans believe that she is the descendant of Bastila Shan. It is also stated that she may be able to use battle meditation, Bastila's most distinctive ability.
It is not currently known whether Shan will play a role in the upcoming video game Star Wars: The Old Republic, because in a press release BioWare revealed that the story in the comic Star Wars: The Old Republic, Threat of Peace Act 1: Treaty of Coruscant will span the three decades between the Treaty of Coruscant and the start of the game. This possibly places Satele at an advanced age when the game begins.
"She will destroy you..."
