I use the script below, which apart from needing a way to see the message
id of mails is independent of any mail tools. For git send-email generated
series I use it as:

    ~/get-msgid -g '2 5' '    <    1447415999-22003-1-git-send-email-olaf@aepfle.de    >    ' | git am

(where 2 and 5 come come from the message id of the first and last patch
mails and it will apply the whole range, note that git send-email often has
patch #1 with msgid=2 due to the cover letter)

Sure, but none of that is a blocker for what Doug is actually asking for
feedback on here, which really doesn't need to go off into the weeds
regarding some other future workflow which it may or may not enable, in
order to make a decision.
