Sulfur Cave Surface Biome More Common

The newly added Sulfur Cave Surface Variant is a very nice add. But this biome is very hard to generate, basically one in 10 sulfur caves have the possibility to generate on surface and a lot ends up generated bellow water. 
The sugestion is to increase the rate of Sulfur Caves that goes on the surface, maybe making one above a big lake of underground lava or above half of the sulfur cave biomes.
This would improve the world generation a lot, and other biomes are already spawning every time another biome is near (like pale garden that spawns with EVERY dark wood forest)
