I like the idea for compatibility with modded dimensions like Twilight Forest and Aether. I think it would be really cool to add towers for Deeper and Darker as well. It's a really good mod that adds the Otherside dimension that expands on vanilla content like the deep dark biome and ancient cities.

Deep and Darker looks like a really fun mod! We have some interesting stuff planned for the vanilla deep dark biome and ancient cities as well.
I will definitely add it to the list of dimension mods we plan to add content for, like Aether and Twilight Forest.
