Your disk setup allows to do this comparably easy, but I would think
twice whether that is actually what I want to do. You end up with two
systems which you have to maintain and, most importantly, you cannot
properly share your /home. Most programs that save their settings to
$HOME will automatically upgrade their configuration files on first
start with a new version and after that you have to assume that the
older version cannot read it anymore. I realize that this is part of
your disk space calculation but I want to stress that the result is
probably not something that you will want to use for an extended period
of time.

You can vgreduce debian-vg easily to make room for your planned
debian9-vg.

Yes, it will. It should also be possible to vgreduce debian.vg and
vgcreate debian9-vg inside the installer, but I would be more
comfortable doing that from the running system, using the regular tools.
During installation, you just have to make sure that all LVs in
debian-vg are marked as "Do not use".

It happens to everybody. The only things that help are a good plan and
concentration on the task at hand. :)
