That triangle is irreplaceable. I would've given it a lovely death in a reboot and then just let co-matriarch's Alexis and Krystle glide in and out of supporting roles every few episodes to war over the fates of their brood and sometimes the memory of Blake. The female rivalry, though, has a place. It's essential. In Dynasty, two women need to fight. It is law. And replicating an undoubtedly lesser, but still captivating degree of the glittering anti-chemistry that was Joan and Linda would be easier to try to "fake" "make" than the accidental alchemy of all three. The best bet at keeping the original "rivalry" energy moving forward would have been to cast the living daylights out of Krystina and Lauren and place it between them. They could fight over any and everything including men, position, power. They don't need their own "Blake" because vis a vis the latter two things, they would essentially be waging their own rivalry over his legacy and their respective places in it. That's the gag... Blake's unseen but palpable presence in everyone's lives even after his death. In a way, he'd have been the Roger Grimes of a reboot. All the best moments haunted by his memory. Because Blake was part of everything of value in their lives, whatever it was, he'd always be symbolic of the thing they'd all be obsessed with, fighting over, or unable to escape.
