Maybe I misunderstood original goal but what I had in mind reading this
is certainly not editing a priviously received message in order to
(re)send it again but sending a postponed/draft message which, I guess,
means no full header(s) (no received header and such and probably
partially filled header, if any).

On the other hand, doing just something like:

C-x mail RET M-x text-mode RET M-x message-mode RET

does no harm to the buffer content as far as I can tell thus, I guess
amdragon suggestion is by far, the best compromise.
