Combining the Nether Forest Fungus Biomes

Honestly, I do not understand the point of having two virtually identical new biomes added. Sure the sort of variety is nice but it's kind of not worth it in their current state. So, I believe there is a very unique way that could really spice up a "tree" filled, nether forest biome. I say, make the first ever dynamic biome, one that changes every couple of set amount of ticks into its twin variety. Every time a nether forest is generated, it's a 50/50 chance of which one it will start as, and after said ticks pass, it shifts color and theme into the other.  More interestingly though, I was thinking that each type of forest has its own set of mobs and feel. Warped would be considered the passive state where Hoglins do not spawn, striders playfully pitter patter in small lava ponds, and maybe a new passive floating mob that could float you up to higher parts of the dimension above if given a treat. However, when the brush turns crimson, it affects nearby lava, turning it to magma blocks, closing the strider ponds and creating jagged magma block shores. Striders will grow cold and wander off to the burning sea, hostile hoglins will come out of hibernation, and those quick travel flutter flies will turn hostile and pick you up from the ground and drop you from high heights. I think this is a really unique concept that would fit the ideal nether PERFECTLY and add some dynamic behavior to the game world.
