West has been on and off for a while. the old boats had a risk of people exiting them and getting into the surrounding areas. they've used the west theming for premium experiences too. It's also the closest to the rear residential area and while there is a scream shield I think the noise is still an issue for them. I don't see any issues with West being offline TBH.
As for WOZ, I think WB would be very protective of their IP here. While there is a great opportunity for flying monkeys or scarecrows, woodsmen and the like, I just don't think such a classic should cross over into horror genre in park - at least not yet. Though it's a shame they won't open the land for capacity reasons I suppose...
