@KentPfeiffer or
@CaliforniaSue may have some insight or check in the ask forum as well.
If it's worth the research, maybe check with another renowned hybridizer if possible. Keith Keppel is in a look at pictures mood lately, and may know exactly. Look up Keith Keppel Iris and his email is posted on the site. He usually responds later at night, but may add direction.
Ps. Make sure to show us a bloom. Always starving for bloom pics
