The highest code level for DS8880 is R8.5 according to the latest IBM support page on DS8000 family code. So, no R9.
I don't believe that you can have Global Mirror with two targets (although I'm ready to be corrected) but I think you can cascade sessions. There's a data migration example in section 47.1 of the DS8000 copy services redbook, SG24-8367-01. Does that come close to what you want to do?
