Probably not for the first four. I think we should stick as closely to the original as possible. But when it comes to artifacts, we need to take a look. If we have to add something to each map, then forget about it; I definitely won't be doing that.
I wanted to ask what the arena and changes in SmallSpecialArena_Grass_Custom are. The file is large, and comparing them is very tedious.
This is an arena for video clips in the Agrael vs. Elves campaign.
It was almost empty. And because of this, there were bare fields in the videos and no textures. If you want to see how it looked in the old AllCampaigns: almost all the videos in mission 3 for Agrael, the first two videos of mission 4 for Agrael, and the first video of mission 1 for Railag. There simply weren't any textures. I drew it approximately like the original, as best as I could.
