If the FCC only permits voice communication on CB, doesn't that
prevent deaf people from using the band?

Yup.

I think TTY, as well as CW,
should be permitted for that reason alone.

Interesting but I doubt it's all that practical for hearing impaired users.

For TTY you need a clear channel, i.e. one transmitter at a time. So how
often do you think that's going to happen and are CBer's displined enough
not to try and jam the TTY station?

For CW the same thing however you would need some expensive filters to get
more use out of a 10 KHz wide channel using a mode that needs anywhere from
300 to 500 Hz at most. The transmitting station needs a way to move it's
signal around on the channel etc. so more that one can use the extra
bandwidth. Using different tones for each station would work, but then you
still need the narrowband filters at each end to selectively filter the tone
for the one station you want to hear.

If it became a petition,
would it pass?

I don't think so from an operational stand point. Too many problems and
besides they would likely use "texting" on their new cell phone anyway. It
does what you proposed already.
