Drum Island Doctors

I was thinking, and came up with the idea of a Drum Island fortnight. The main boss is Dr. Kureha, who, when under 20%, uses Doctor Bomb, which causes her to heal to 80% of her max health, with an alternate that is Dr. Kureha and Chopper, who enrages if you defeat Kureha first. The miniboss could be Chopper, possibly in a new form (maybe wearing a doctor's outfit that's way too big for his Brain Point form, and his evolved form is him in Heavy Pont with it actually fitting. At 20% or lower, he uses his special/ability, Doctor's Apprentice, which heals him up to half health and boosts his attack by 1.75 times. The secret boss could be Dr. Hiriluk (as an excuse for him to finally be added) and he could start by using his special (let's call it Quack Doctor's Mixture) that reduces your HP to 99% of its max... But also makes his cool down 99 and gives you 20 turns of a large auto heal. Think it's easy? Think again. When he reaches 20% or below, he uses Quack Doctor's Mixture again, which clears all buffs and debuffs, enrages him, multiplies his attack by 100, quadruples his defense, despairs both captains, binds your entire left side for 7 turns, and poisons you. So... Burst him above 20%. The condition to make this difficult? Extreme Cold. Every turn your team takes damage from it, Drum Island residence don't, Luffy doesn't until the boss, and Nami takes double damage. If you have any ideas, comment them! I know this will most likely never make it in, but hey. It's a thing
