Custom Campaign Maps

I’m extremely excited for custom campaign maps. I’ve played two for CE and one for 3 and they were all really enjoyable (besides the rebalanced weapons/enemies). Currently, there are only two available on Steam Workshop though. I know campaign missions take much longer to develop than multiplayer maps, but is anyone here planning on making custom maps for the Halo games? I would absolutely love to see custom H2 and Reach maps in particular.
