Would a Trade of Eli Manning to the Colts be Impossible?

So I'm sitting here on Sunday afternoon watching our Indianapolis Colts and thinking how much we folks in Indiana love our Mannings. Peyton Manning gave us many years of excitement  which included a Superbowl victory. Now that Andrew Luck has retired and Peyton's younger brother Eli had been benched by the Giants, would it be a fitting end for Eli's career to bring him to Indy? Given that Eli has a no-trade contract and current Colts QB Jacoby Brissett is playing pretty darn good, maybe this is not something that would work. The Colts have an expensive backup QB in Brian Hoyer who has been signed to a three year deal. BUT in my fantasy world, Eli comes to Lucas Oil stadium and leads the Colts to a Superbowl.
