Player respawn timer?

[Master of Disasters]

So I was wondering to myself about creating a sort of deathmatch kill cam that puts the killed player in the eyes of their killer, now I know that's fully possible to do, but with Doom's fast paced environment and standard near instant 'press use to respawn' function, a kill cam would probably go skipped and unseen by most, especially if an ally cam was added if you waited long enough after death, as well watching the kill cam and not respawning immediately would give you/your team with a disadvantage of not being in the fight.
Knowing all too well that all ACS commands that lock player controls do not lock the use key (probably to prevent ACS griefing as it also stops the player from restarting the stage), my only conclusion was to temporarily render a player invisible, control locked, and non-interactive until the timer ended, and then set them back to normal after, as well as end their ally/kill cam. My issue is that teleport fog would still appear when the currently locked player has respawned during the countdown, and not when the countdown reaches 0, which feels a bit too off for my liking, same for spawning another teleport fog. If anyone has a better method, I'd be all (ears? eyes?) to learn it.

tl;dr Is there a way to disable the use key in multiplayer to stop respawns, or just temporarily stop a player's respawn?

Was also trying this exact same thing, except with Lives instead of a timer! Will definitely let you know if I figure it out. Or, if you've already figured it out, would really appreciate it if you let me know how.
