There was an item in SOD around 1986 or early 1987 suggesting a Hope return, possibly with Alan-Michael. I guess the show, heavy into the teen market and also full of a lot of women in her age range, decided to just age him and not bother bringing her back.
As for the Santos and the Winslows, I liked them more than I should have (other than Pilar, who always bored and annoyed me), because of the casting and because for their flaws I thought B&E did a decent job with their material. I thought the Labines were very tone deaf about what worked for the characters - Edmund as some sort of dark prince with Beth as his dim bulb enabler was unwatchable, as was Danny as the Sonny Corinthos of Springfield. And then after that it never really worked - likely it wouldn't have anyway. I will say I liked Danny/Cassie - it's a shame the show caved to pressure from "Manny" fans.
I do think it was a huge mistake to bring Bradley Cole back as Jeffrey. I know he had a lot of ardent fans but what charm and style he may have had as Richard was MIA in the truly disgusting Jeffrey (as was any chemistry he had with Laura Wright). David Andrew Macdonald was a much better lead in an antihero sense and continued to be a highlight of even the dumbest stories (like the "evil Will" tedium). He also had a great, great ass.
