I would have to also hack the email client since I don't enter my 20 character
high entropy password when I send or retrieve email.
You really need an email standard to integrate TOTP. To be realistic, you need
Gmail to use it. Whatever Gmail wants is essentially a defacto standard. I live
in the real world, so whatever Google wants, I comply.

You can bodge it for HOTP/TOTP hardware token generators. Dovecot allows
custom plugins to check passwords. The plugin can take passwords of
the form {password}+{2fa-token}, then split each part to check against
authentication systems to check validity.
