A. Bertram Chandler's "Hornblower IN SPACE!" John Grimes met, in one book, not only his own alternate self, but Poul Anderson's Dominic Flandry, at a point where space-time was somewhat chaotic.
Another tale had Grimes accidentally drop in at a social club for explicitly fictional naval officers ... such as Hornblower, of course, but also Captain Queeg and Commander Bond; they bent the rules a bit (as well as Queeg's arm) to let Captain Ahab in. The major-domo there was Jeeves, who asked Grimes, "The question is, sir, are you an enduring creation?"
Shortly afterward in the same book, Grimes found himself reading over Chandler's shoulder....
So it wouldn't be all that shocking, including to Grimes himself, if he met the Loon.

Big Brother is watching you ... and damn, you are so bloody BORING.
