What classic literary character would you like to see dropped into a different classic novel?

I was just thinking that it would be interesting to see some of the biggies (or even minor characters) in classic literature, be dropped into another piece of classic literature, either by the same author, or better yet, a piece by a different author of classic literature.

What if Uriah Heep, from David Copperfield, was dropped into Wuthering Heights, in place of Heathcliff? I thought Heathcliff was a creep, but apparently many people see him as this tragic romantic character. Do you think Cathy would have been repulsed by Uriah Heep, enough to stay off the moors with him? Or maybe she would have thought he was sweet, and tried to “fix” him like women are prone to do with broken men. And would Uriah Heep have used Cathy’s connection to the kind, but well off Linton family, to insinuate himself into that family, leaving Cathy to slink back to Wuthering Heights?

What classic literary characters would you like to see dropped into another story, and how would that play out?
