The role I'd like to see Shatner in would be Tiberius Kirk. Whom I envision as a bit of a rogue and scoundrel. A deep space merchant who plies his trade in a rundown ECS ship on the edge of Federation space.
I also want to see this exchange:
Spock: Hey, pardon me for asking, but who's the little old man?
Kirk: Uh, what little old man?
Spock: That little old man.
Kirk: Oh, he's my grandfather.
McCoy: Your grandfather?
Kirkl: Yes.
McCoy: That's not your grandfather.
Kirk: It is, you know.
McCoy: But I've seen your grandfather. He lives in your house.
Kirk: Oh, that's my other grandfather, but he's my grandfather, as well.
Spock: How do you reckon that one out?
Kirk: Well, everyone's entitled to two, aren't they?
