Yes, easily.

For new installs, yes if the installer UI allows it.  For
existing installs, maybe, but it would be fragile at best without
some sort of device-mapper trick like Android uses.  It would be
more robust to reinstall.

In the future, it would be much better to adopt Android's update
system, which solves all of these problems and provides features
like update compression.  AOSP isn't open contribution, though,
so this is likely to be a fork.
