AFAIK, you can open a .ba-file, if that .ba-file is TEXT/ASCII.
You get such a file, by saving a BASIC program as follows:
SAVE"BASPRG.BA",A
Attention, use a different name than the original .BA, and the ASCII version
takes a lot more place.
I've never done it, but I suppose that way you could also open it for
read/write by another BASIC program. You'd be reading an ASCII data file, no
matter what the extention. I think.
As I don't have a Model T handy - @ work - someone else should test this. Let
us know.
Converting back to tokenized BASIC code, should be as easy as opening the ASCII
.BA-file and saving it again. The tokenized BASIC should overwrite the
ASCII-format.

That is correct, but that's what a user can do interactively from the keyboard,
with no pre-existing basic program in basic.
For his problem, he wants a running basic program to read and write a .ba file.
How could you have a basic program that loads a .ba file, without overwriting
it's own self and immediately crashing to the ground? I don't think there is
any such thing as "load file.ba, offsetting all line numbers +5000 along the
way", then later "save lines 5000-10,000 to foo.ba, offsetting all line numbers
-5000 along the way"
That said... teeny is an assemby program, which can manipulate .ba files. But
teeny itself is created from a .ba program...so, it *seems* it really only
depends just how Rube Goldberg you want to get, and just how much ram you are
willing to spend on embedding a data-encoded assembly program into the basic
program, just so it can be unpacked, used, and removed. ;)

If you have a .do file and you load it from basic, if you save it, it will save
as a .ba file. Or am I completely not remembering how this works?

Ya, that's what I want to do. The .ba I want to write was originally
read from the same box. So I know it's a valid .ba file.
I just don't know how "special" they are (sort of like the
restrictions on the .co files).
