The irony is that he did ask to and Rick Berman shut him down despite no other cast member being turned down after Frakes broke the seal. Dude got fucked over so hard.
The more I learn about behind-the-scenes stuff on various Star Trek productions, the more surprised I am that so much of it turned out well despite the abusive assholes who ended up in most of the producer and executive producer roles. Berman and Kurtzman are the real villains.
