Yes, that should work: settrans myroot unionfs / --mount overlay && chroot myroot (BTW, this is an obvious use case for union-mounting with something different than the underlying node -- why didn't I see this before? I'm glad now that we decided to go with the --mount option to unionfs: it's so much more powerful than a "pure" unionmount :-) ) > The goal is to have / with some modifications.

I have contemplated it a couple of years ago; and we actually discussed something like that a while back, in the discussion about allowing users to locally install packages with dpkg. This is very relevant, as this thing won't work smoothly without integration with the package manager -- any upgrade to the global system could break my local environment otherwise. Don't remember whether we explicitely talked about this point in the previous discussion. -antrik-
