This is already possible, see "5.2.1. Debian Installer Parameters" in
the manual [1] :


    This boot parameter controls the type of user interface used for the
    installer. […]
    DEBIAN_FRONTEND=text may be preferable for serial console installs.

  debian-installer/theme (theme)

    A theme determines how the user interface of the installer looks
    (colors, icons, etc.). What themes are available differs per
    frontend. Currently both the newt and gtk frontends only have a
    “dark” theme that was designed for visually impaired users. Set
    the theme by booting with theme=dark. 

While the "text" frontend is less usable than the "newt" frontend, a
monitor able to display Linux boot messages will be sufficient to
perform the installation.

The "dark" theme should be enough for monochrome monitor as well, but I
cannot confirm this.
