Any ideas on creating continental world generation with mods while retaining Terralith (and maybe Tectonic)

I’m trying to play Minecolonies with ~40 other mods and my biggest gripe is that biomes are very small (even with large biomes) and the oceans are very small and unrealistic. Ideally, the world would be made up of very large continents with realistic biome dispersiton (no savannahs next to every plains biome) and vast oceans. I’m also hoping to retain the use of Terralith and Tectonic for their biomes and generation. I know this is kind of a big ask but this is truly the one thing I feel is missing from my game. I’m looking for any type of mod, tool, or suggestion that I can achieve this through. Any help is much appreciated.
