Add a huge spider boss inside a Underground Biome

Can we have a HUUUUge spider Boss? Where you need to destroy all legs first, then the abdomen while it keps on spawning eggsacks that hatch spiderlings and it spits sticky webs to slow you down or render you not able to use glider and add poison damage, and its area is in a huuuuge dimly lit underground cavern??? basically a Underground Biome~
