That's actually a really well-thought out theory (and it incorporates 
a lot of unanswered questions), although I'm not sure how much I buy 
into it on the whole.  I can't see Voldemort being even *that* 
merciful- I doubt he ever would have trusted Snape again, certainly 
not enough to accept him back when he returned late at the end of 
GoF.  But...I love the idea of Snape's family being in danger.  I 
strongly believe that the reason DD is so sure of Snape's loyalty 
DOES have something to do with Snape's family (although I always 
theorized it had to do with Irma Pince, who I think is Snape's mom).  
Your theory also hits on something that has bothered me for a long, 
long time:

(from JKR's rumor bin)
Rumor: Luna is Snape's daughter
JKR: This is a most tantalising idea, but no, Mr. Lovegood, the 
editor of 'the Quibbler', really is Luna's father and Snape does not 
have a daughter.

Doesn't it seem odd that she says "Snape does not have a daughter?"  
I would think that it would be much more natural to just say, "Snape 
doesn't have any children."

Another quote that is relevant to your theory:

One of our internet correspondents wondered if Snape is going to fall 
in love. 
JKR: (JKR laughs) Who on earth would want Snape in love with them? 
That's a very horrible idea. 

She chooses to answer the question by saying, "Who would want Snape 
in love with them?" rather than saying something like, "Snape doesn't 
have the capacity to love," or just an outright, "No, I don't think 
so."  She says "That's a very horrible idea," but is she referring to 
the idea that Snape could be in love with someone, or the reaction 
that person would have (I hope I'm getting my point through there)?
