coop mode. falling instead of dying.

[NightWalking88]

Hi all! Can someone make a mod for falling instead of dying and helping an ally so that he can be picked up? I really love the hardcore mode with one death. But when playing in co-op, this mode is inconvenient due to the fact that someone on the team can die, while the rest are alive. Who can make such a mod? fell and wait five minutes (customizable parameter), for example. If you pick it up, you come to life. If not, then that's it - he's dead. By the way, is it difficult to make such a mod?
