Yeah, it is possible. But how about thihs?
I have been thinking a lot about the Marauder's map while I was reading 
the books and I could never quite figure out how it is possible that 
Harry notices only a couple of people on the map. I mean, if it would 
show all the people in Hogwarts, it would be pretty crowdy and 
confusing. So when I was reading the posts on this topic the thought 
came to me that maybe it shows only the people, who are known to the 
user, on the map. That would explain why F&G and Harry (who imho would 
be suspicious to see an unknown student around Ron all the time) can't 
see Pettigrew, and why Harry won't see Sirius, who should have been on 
the map, because IIRC the shrieking shack was on it as well, and he 
(Sirius) is roaming the grounds a lot, where Harry sees him in dog form.

It might explain why Snape doesn't see two Harries and Hemriones, 
because he doesn't know the futureHarry and futureHermione

I haven't thought about it at length, so I'mcurious to know what your 
thoughts are about this.
