Hmmm, a possibility ... we don't know enough yet about the veil ...

Anyway, your post did remind me of the scene in CoS where Harry sees 
the picture of escaped prisoner-Sirius for the first time (I believe 
it was in the paper of Uncle Vernon - no books at work, sorry) and it 
reminds him very much of the Vampire pictures he had seen in his DADA 
classes the previous year. Foreshadowing?

BTW, someone mentioned in a post not too long ago that JKR said in a 
interview that Dementors originate (erm, not quite the right term but 
can't remember it) from fungus. So that would IMO rule out the 
possibility that Sirius becomes a dementor.
