Take this with a grain of salt, but theforce.net http://www.theforce.net/story/front/Ep... is reporting that one of the Episode VII characters currently in casting is for the biracial progeny of Jedi Master Obi-wan.
If this is true, wouldn't it be great if one of the spinoff movies was an Obi-wan film starring Ewan MacGregor about his time in the dessert and finding a love interest and ultimately and sadly having to separate from her for her protection?
Having the daughter/granddaughter be part of the new generation of Jedi already trained by Luke with her own back story being unveiled would be bonus as well.
This also is encouragement that the producers are committed to a diverse cast while keeping it rooted in the originals. It would have been really easy to make Lando Calrissian's child the diverse cast member, but also disappointingly predictable.
