email headers

I send an email from me@mydomain.com to joe@joesdomain.com. Would it be
possible to alter the email header in such a way that when
joe@joesdomain hits reply and responds to my email that it could be
redirected through a third party domain and then to me@mydomain.com

This would need to be transparent to Joe i.e when he hits reply all he
sees in the "To" field is
me@mydomain.com.

Could this be achieved without having to change MX records?

Thanks for your help

Yes, you can use the "Reply-To:" header, so that Joe's reply gets sent
somewhere else. Arrange for the somewhere else to forward it to
me@mydomain.com.

It wouldn't be "transparent", thankfully. This would be an appalling
security problem, were it possible. Such security holes aren't normally
coded into RFCs. At least, not knowingly.

Please to tell us, why do you want to perform this trick on one of your
correspondents?

(like "aa"), remove half of them (leaving, say, "a").

If you control the mailserver for mydomain.com you could accept mail from joe
and redirect it yourself to that third party. And have the third party send it
back to your mailserver (probably on a different port).
