Pettigrew hasn’t spent the last eleven years as the Weasley family pet, because that would be ridiculous, but I doubt Sirius Black is guilty. At the very least, it would require more than obvious consistency preserving changes to justify that.
I’m not sure whether Sirius Black is guilty, but I don’t take his canon innocence as significant information on the question. That’s what I meant by “overwrite” as opposed to “reverse”: the new state is mostly uncorrelated with the old state.
