It's cool, and you don't must have Minecraft now to be in Hardcore mode, but I think you might add some bosses because the onlyn mod that add monsters in Minetest add monsters thats aren't dangerous when you have a good armor. Just add a possibility to come back in creative because else, if you made an awesome world, with good builds and you die before have been able to show it to others, it's dommage. Else, good idea.
