As an alternate, these guys will cut a pad set out of PFC material if they can get a stock pattern. They did that for Brembo 6 piston monoblocks.
They'll also do it from Porterfield material but PFC seems to be more highly regarded among hardcore trackies.
Hopefully Pagid will make a pad soon.
Good luck, let us know what you find if anything.
