I`m not sure if this is sensible, as authorship information is baked
into the commit at the time of committing, which (usually ;) happens
before you get to 'git push' to the other repo.

If possible, changing this info after the fact, on 'git push', would
influence the existing commit you`re trying to send over, so your
'git-push' would have a surprising consequence of not actually
pushing your desired commit at all, but creating a totally new commit
inside the other repo -- this new commit would be exactly the same
patch-wise (in regards to differences introduced), but because of the
changed user info it would be considered a different commit
nonetheless (different hash).

Otherwise, as you already stated that you find the current local (per
repo) user settings override logic inconvenient (error-prone), you
might be interested in approach described in this[1] Stack Overflow
post.

In short, it uses a template-injected 'post-checkout' hook (triggered
on 'git clone' as well) alongside '.gitconfig' (global) settings to
achieve what seems to be pretty similar to what you asked for (but
might be a bit more sensible), where you may fine-tune it further to
better suit your needs.
