I might have a set of OEM rotors for sale soon. I'll PM you when I find out.
The biggest issue I see is structural integrity especially with drilled rotors. My experience is that heat cracking becomes more of an issue as the rotors become thinner. Not too bad with slotted but terrible with drilled rotors.
