Amanda, AFAIK, talkback is open-source, so, it could be modified, but,
one of the reasons I got to playing with a pi in the first place,
besides raspiVoice implementation of the vOICe is the overall mini-pc it is.
For example, a while ago I was one of the hardware beta-testers for a
form of stand-alone PC implementation this side, which was basically
modified hardware to implement a full PC in something that felt like a
rather bulky keyboard, since all the PC hardware is built into the
keyboard housing, and, it's based on the command line version of ubuntu,
running off a menu system from boot-up, and then also allowing you to
launch a version of the ubuntu gui/desktop from there, but, for example,
the raspberry pi can currently offer almost all the same functionality,
for a very small percentage of the pricing, but, does require
configuration/setup, and, slightly less convenient hardware/wiring,
etc., but anyway.
In other words, I would definitely recommend sticking to the raspberry
pi as a base for something like this, and, while not really relevant, I
have already managed to get my own python-code-based bootup menu going
on a pi 3, working with an external USB audio adapter to then offer a
boot-up menu relating to recording audio, etc., but anyway.
Stay well

However, I strongly dislike being forced to use Talkback and BrailleBack.
Correct me at once if I'm wrong about any of the following:
* BrailleBack is inferior to BRLTTY.
It's dependent on Talkback. We can't add functionality to it, e.g.
latex-access.
* We can't add functionality to Talkback.
We must depend on our Google overlords for all improvements to this
screen reader.
* But we can modify Orca, Fenrir, BRLTTY etc.

Android's massive install base may seem like an asset, and I'm sure===========================================================
blind persons already using Android would probably prefer improvements
to the quality and quantity of accessibility options on that platform.
That said, consider the following:
-How many existing Android devices support ethernet and USB peripherals?
-How many existing Android devices aren't built around a touchscreen
as the primary input/output device?
-How many existing Android devices support installation of custom OS
images without voiding the warranty?
-How many existing Android devices come anywhere close to the 100USD
target cost?
Not to mention that a general Android solution would need to run well
on a variety of hardware whereas a Pi solution gives a specific
hardware target and one that packs a lot of computer into a little
space and at litle cost.
Now, if there's a well supported Android image for the Raspberry Pi
I'm unaware of, there might be value in checking how existing
accessibility options work under it compared to Rasbian and possibly
choosing it as a starting point over Rasbian or even trying to produce
a Pi image that can dual boot the two.
And hardware concerns aside, what about the following considerations
regarding the Android OS itself?:
-Can Android run in text-mode?
-If so, how does the volume of text-mode applications available for
Android compare with the volume available for Rasbian(or even vanilla
ARM Debian)?
-Does Android support running a GUI that wasn't built with a
touchscreen in mind?
-Has support for writing Android Applications in languages other than
Java improved? Does there at least exist a stand-alone C++ compiler or
Python interpreter for Android?
Android may have an advantage in terms of install base, but unless my
knowledge is even more incomplete than I think it is, it seems clear
that Rasbian has the advantage in flexibility and versatility.
