I think there is something good in this idea. It would require
rewriting the rethreading code, and to write some code to remap
MIME-types, but it would work. We also could use the ANNOTATE
extension in IMAP, not that any server I know of implement that today.

However, I think it would be cleaner to add a new function,
`gnus-delete-and-insert-edited-copy-of-article', and have the editing
commands in Gnus updated to fall back on it if the backend doesn't
support replacing.

Anything else sort of feel like writing extra code to work around
Gnus' behaviour.
