I should also add that the selected person shall not be allowed to leave the clan war to break the replay.

ALT + F4?

OT:
A big part of the people who play GunZ don't have a good connection though, even an upload of 100-300Kb would make them lagg for a bit.
People could also just delete replays right after the recording.

Then they wouldn't be allowed to rejoin.
There would be no reason to delete a replay besides hiding sensitive information mentioned in team chat (in that case, try to prevent team chat from getting recorded if possible).

Addressing the uploading concern, it should really only take a couple seconds (the amount of time it takes to queue up and enter another clan war).

I'm pretty sure 90 percent of the most active players wouldn't mind this system. It would, in fact, bring back a lot of players.

Or have a bot that records the clan war on its own, not from the player's perspective. That would somewhat kill the main purpose though.
