Fuck me! I would kill to see Klaus Kinski as the Nihlist. I'm not sure FZ would make a good Dude, however. Zappa was way too loquacious and cerebral to be the dude, and he was always adamant about not doing drugs. I know its acting, but c'mon, doesn't fit his personality. Jeff Bridges, like the Dude himself whom he was playing, was the right man in the right place at the right time.
