A grapheme combining character would only be usable if a normalized combined character was also defined, and the mapping between the combined characters and the un-combined characters with combiner. In other words adding such a thing wouldn't solve the problem you've posed (adding a combined sj character) since combining characters are (as I understand it) intended to be ephemeral and only fully combined characters are inteneded for communications.
