NHF – new heroes for Heroes V 3.1.

It depends on the map. If it's heavily scripted, the scripts might break, but if not, everything should be fine.

Can the map be uploaded?

The map is script-free and was created in GSC. I just noticed that when not much is explored, the AI moves faster in single-player than in multiplayer, so I play single-player using multiplayer maps with AI opponents. By the way, when will we see heroes with specializations for treasure rooms? Aren't they (treasure rooms) already fully script-based?
