I'm not sure if you should play as someone real. Their fans might have a problem with what you write.

Can you write a fictional character? Even if you made it an unknown slapstick comedian that died of a stroke or something, then you could keep most of the bio, it would fix that problem.

Also, what reason does he have to rebel? At best, he seems like a spy or someone to distract the gods, not a freedom fighter or someone who wants to live again, especially if he still enjoys Elysium.
