Buffy the Vampire Slayer Vs. The Confessor

I lost track of it in later years, but I was a big fan of Kurt Busiek's Astro City for its first few runs.  The Confessor story arc was among the many highlights of the series for me.  With such a rich world that Busiek (and artists Brent Anderson and Alex Ross) created, I am surprised that I have never heard any talk about adapting it for TV.  It seems like a perfect candidate for either a live action or animated treatment.
