"borg recreate --exclude" or "--pattern" can do that, but it requires 
some free space.

be very careful with this (do "--dry-run --list" first) as this could 
unintentionally remove data you wanted to keep, IF you specify wrong 
exclude patterns.

yes, recreate. it will still take quite some time.
