Not the same person, but this would be really helpful for me. While there are a lot of options, I feel that some options are missing that I would really like to use to get a bit more freedom in the layouts I would like to use.
What about trees with snow on top, that are still on a grassy plain. Mountains that are on a grassy plain or on top of rockland_grass. Plains, maedows and marshes that are used on the darker green. Corals and rocks in dark water or a maelstrom in light water.
