The only character that didn't get tainted by the prequels was Han Solo (which is surprising considering he his arguably the most popular) so to get the 'scoundrel' back into a galaxy far,far away (and asuming they go with the characters that appear in the hundreds of book and comics that already act as sequels) the best option would be to add the rougish Dash Rendar.
But with his recent drop out of the Logan's run remake and lack of a big budget blockbusting headliner Hollywood favorite Ryan Gosling could be the house wives favorite....
