Hmm. I have added a new user option, `tramp-default-rename-alist'.  Here
you can specify your preferences for renaming.  If you always want to
rename files from "/ssh:badhost:/path/to/dir/" to
"/ssh:goodhost:/path/to/another/dir/", add the entry

("/ssh:badhost:/path/to/dir/" . "/ssh:goodhost:/path/to/another/dir/")

See the Tramp manual for other examples. Maybe this helps you?

That won't be possible. You must say both bad and new host, and confirm
them. So you have at least two prompts.

Maybe we can change the third argument of `tramp-rename-remote-files' to
NO-CONFIRM? In case it is non-nil (via a prefix argument of the
command), the new host is taken from `tramp-default-rename-alist'
without a prompt, and the buffer file names are changed also without a
prompt? Then you would have indeed only one prompt.

And you must live with the consequences, if the defaults are not as you
expect ...

WDYT?

Best regards, Michael.
