It seems to me that it ought not be over the brink, just very challenging and a major multiyear breeding program. It would take a determined, stubborn person, young enough to put more than 10 yrs into the process. I wish somebody would try.
The biggest problem they would encounter in trying to get good breeding material (assuming they could collect even a small group of historic survivors to start with) would be finding irises with desirable modern traits as pollen donors. I say desirable, because tastes vary so much - therefore desirable to the breeder. Most modern breeders either go to great lengths to control diseases, or make selections in such a different climate, there's not a lot of selection amongst 'the best' for disease resistance that would be critical for hot & soggy zone 10.
It does look like Dallas is very close to the calculated chill isoline for zero chilling hours.
Bob Pries, want to organize an AIS bearded iris plant collecting expedition to Dallas during TB bloom season?

Post it to iris-photos as an attachment. Folks have done that in the past.
