Harry--the Heir of Gryffindor?

I like the idea that Harry is the heir of Gryffindor and that this is 
why Voldemort tried to kill him.  This has yet to be established by 
JKR, of course, and I don't think the theory is totally complete: 
obviously there is a lot more to the story.  But if Harry is 
descended from Gryffindor through James, and Voldemort was trying to 
kill both Harry and James because they were heirs of Gryffindor, this 
might explain what happened to Harry's paternal grandparents. One or 
both of James's parents had to be an heir of Gryffindor too, so maybe 
Voldemort finished them off before going after James, and this is 
what gave James the warning that Voldy was after him and caused the 
Potters to try to go into hiding.
