I have never tried the sorrows with dreamer. Could work.
First time I played coppelus, he died doing nothing. That happenned the first 3 times to be honest. Once you manage to play him right (big fan of on dreaming wings here), he is phenomenal. I've played him with pandora a lot and he is really good. Just make sure he survive early, charge with high cards to build plucked eye and he become a monster.
