I wouldn't mind some Environmental/Biome Backport compat where the cherry trees in the Environmental biomes are replaced with the backported ones from Biome Backport.

Sorry, but I do not support mods that I don't play. However, you can do what you're looking for pretty easily using https://www.curseforge.com/minecraft/mc-mods/block-swap. Hope that helps!

Oh damn this mod looks incredibly helpful for something else I'm dealing with
