Tall (XL) Roofed Forest Subbiome

Over the years many biomes have been updated by adding a bione variant that makes world generation for those biomes more varied. I think this could be applied to the roofed forest biome in which there is a Tall Roofed Forest Biome. I have always imagined it as a forest of pure darkness with trees that rival Jungle Trees in Height. There would be random patches of cracked stone bricks that add to the intensity and mysteriousness of these woods. With how dense the roofed forest trees are it id hard to appreciate the biome which is how I started imagining a Tall Roofed Forest. For most players it is easier to just run atop the trees to avoid all the dangers. Having a sub biome of the roofed forest would add so much atmosphere to one of the unique in concept biomes. The old roofed forests would still be in the game but now some of that roofed forest could appear as this new tall roofed forezt sub biome adding more variety.
