Avestan Izha (was Names of god)

I just thought of something. Since z^ doesn't occur between vowels
within a word in Avestan but only out of *s after RUKI and when
voiced by the following consonant, then in an unattested dialect of
Avestan the cluster *-Vz^d- could have reduced to -V:z^- and filled
that empty slot without disturbing the system of contrasts (or
whatever it's called). I:z^a: could then be a borrowing from that
dialect.
