You should already be able to create a smart playlist / collection from an advanced filter, applying that criteria.

You cannot currently create a Playlist based on other playlists – there’s however already an existing feature suggestion discussing that option.
Edit: as you cannot currently filter by audience/critic ratings (only sort by those)… there’s also a suggestion to address that.
