The CLKx6, GENx6 and GENx6-96 only have six outputs and the GENx192 only has eight outputs but I need more to feed everything in the studio. Can I split outputs?

You can put "T" splitters in, but due to the reflections and increased jitter this may defeat the purpose for having an external clock. Ultimately each device with a clock input should have its own direct connection to a clock…
