I think Healing Wish is fine but getting the move should absolutely keep Hazards away from our movepool. It seems like nobody is interested in CAP 33 setting Hazards at the moment, but if we did get them, we're pushed heavily towards wanting to be a Lead with like Scald/Encore/Hazards/HWish. Not sure how well such a set would perform in practice, the main concern is that it's just hella distracting from the main goal.
Whirlpool feels like an okay inclusion to our kit, I don't find this to be a commonly run move nor easy to build with, but the value as a lure/tech enabling CAP 33 to offensively pressure mons that might have gotten too comfortable switching in is interesting. Whirlpool + Encore/Taunt is a scary combo on paper especially with our great Speed, but we are forced to drop coverage to run this and both our STABs are pretty crucial for success. If you run Whirlpool over Scald you're pretty useless into Gholdengo, while dropping Moonblast means any Water immune + Krilowatt are suddenly huge problems. I guess potential Earth Power would be okay as mono-coverage into some of those, but that leaves you very vulnerable to Wellspring and most Ground immunities so it's not really an improvement.
Defog is enticing solely because more hazard control would be great for the metagame, however I do not really think Defog fits our build. If we feel pressured to Defog for the team our gameplan becomes much more exploitable as we won't be spending turns healing or dealing damage. Our STABs + Encore do a fantastic job of actually forcing opponents to play around us, if we're the team's defogger the opponent could easily read us and stay in knowing they could be rewarded with essentially a free turn as we clear hazards. Defog just comes off as a builder trap.
As for sets I'm most in favor of the Fast Wall, Haze, and PhysDef Rough Skin/Anti U-Turn. The Wish Passer set doesn't inspire a ton of confidence but Recover + Wish on a fast mon is really funny and even if our HP is on the lower end having the capacity to ease switch-ins for teammates has merit. I think it's harmless enough to be okay. The Whirlpool set has all the issues I outlined above but I'm not opposed to the idea of it.
