No, you cannot merge switches if their interop mode is different. They need to respond to a certain level of FC-SW (fibre-channel standard) ILS commands and responses before being able to merge.
My advice - ditch the McData and go to native mode on the brocades. It's not worth the hassle to try to fix and maintain your current setup.
