Elemental ghast

I think the dried ghast is underutilized. The giant ghast is great. The fact that cure it with water has me thinking they could be cured with all of the different elements giving them different variants. A lush cave ghast that crawls walls and admits light level. A mountain ghast when paired as a backpack gives slow falling and jump boost. And a lava ghast that admits a heat level for cold biome development or a furnace you just feed magma block too. Speaking of feeding, lush would eat glow berries, and mountain would eat wind charges. I think this would be a great addition to exploration. Leave only footprints. No need to build massive things or tear down mountains when you have a ghast help you do all the things. Besides it would give players a reason to explore the nether more. So they could go on grand adventures without worrying about the details. It hits all the things. I've even worked out a pitch, and sketches of the variants. What do you say?
