Its kind of a hack, but could you not just patch in symlinks in the
right place in the xdg-app system repo.

So, for instance:

mkdir -p /var/lib/xdg-app/app/com.endlessm.OldApp/x86_64/master/
ln -s /old/install/dir /var/lib/xdg-app/app/com.endlessm.OldApp/x86_64/master/old-version
ln -s old-version active

You have to add a metadata file to the app too.

I think xdg-app would pick this up as an installed app fine, and if you set up the right
config in the system repo it may even update it correctly.
