I don't know...
In C major, a first inversion C tonic chord has such a vastly different effect and meaning than, say, a Neapolitan sixth chord, even though they're the same first inversion major chord sonority.
It seems that the context of a chord is much more important than its sonority.
(Or for that matter... a root position tonic chord vs dominant chord, even without the seventh, are so different)
