Thanks for an interesting experiment.  As with 2/3, I suspect that
most of the contents in the patch may be correct, but I'd rather see
these confirmed by those whose names appear in the patch.

IOW, I would not feel comfortable applying a patch, unless it looks
like this (just taking a single person as a random example), 
and I do not mind many such individual patches:

    Subject: .mailmap: unify the same Ben Peart

    These multiple author identities in our history are actually the
    same person.  Map them to the latest address.

It may be even better if we can arraange the author of the patch to
be the one who is involved, with "Helped-by: Stefan".

Thanks.
