Yes. You wont be able to change the history after someone copied it
from you (cloned or fetched), because it's "his" now, but you're free
to do anything with your part (or whole) of the history. Happens all
the time. Look at git-cherry-pick, git-format-patch and git-am (and
the new git-filter-branch, but is more for automated mass-rewriting of
big histories).

Yes, git-format-patch accept pathnames, and its output can be passed
to git-am, which will apply the changes to this file only. git-am also
accepts -pN, so you can move file up a bit. For more complex path
manipulations you'll have to modify the patches (or git-filter-branch
again).

Yep, no problem, just a bit of scripting. Just make sure no one has
that "old" history: it will be hell to merge with them.

no, it is not.

depends on how you write the history for that submodule
