If you hit “Reply-All”, at least when I use Gmail, it includes both the From: and the Reply-To using the scheme below (I tested it out just now). In Outlook desktop I have to also copy/paste the From: address (mailing list). It’s not ideal in Outlook desktop, but I can live with it.

In this email discussion, I hit Reply-All and includes Ted on the To:, and dmarc@ietf.org<mailto:dmarc@ietf.org> and ietf@ietf.org<mailto:ietf@ietf.org> on the cc.

And if there were something like this in other headers that retains the original senders:

Reply-To: originalSender@example.com<mailto:originalSender@example.com>
Sender: dmarc <dmarc-bounces@ietf.org<mailto:dmarc-bounces@ietf.org>>


I don’t think this is quite right—I think the Reply-To needs to include all of the senders or else every reply will be an off-list reply (would cut down on noise, admittedly).   Otherwise this would be a great solution.   But because of the way it interacts with MUAs, I do not think it would work in a way that doesn’t violate the principle of least surprise.
