Reading remote reflogs

Is it possible to somehow fetch the reflog of a remote?

I would like to delegate some post-receive actions to an automatically mirrored clone of some repositories. Mirrored repositories don't maintain a reflog, even with core.logAllRefUpdates = true, so to be able to know what was pushed per push, it would need to somehow know the reflog of the origin.

Of course a post-receive hook can send this information downstream, but I'd like to keep the origin 'dumb' and not do that.
