Which actor should have returned in a different role?

[Monzo]

If Knots Landing managed to bring back an actor in a new role twice, why not Falcon Crest? Which actors would you have liked to see in a new role on Falcon Crest after their character's death, and what should the storyline have been like? Similar to Melissa and Samantha as a coincidental resemblance? Or twin siblings? Or should it not have been mentioned at all that the new character resembled a familiar face?

In my alternative Falcon Crest universe, Robert Foxworth would have come back, minus his beard, as Chase's long lost brother in season 8 - turns out he is also Nicole (Leslie Caron's) brother and Jacqueline was their mother. He is also an agent for the 13, and tries to murder Richard in the cliffhanger to season 8 - a far more dramatic and exciting ending to what we actually got that season.
