I was interested in the possibility of having a Survival Mode category for this game. Would this be possible, considering other CoD games have Zombies categories?

I would gladly take on moderation responsibilities if needed. It seems that it would only make sense for there to be survival along with spec ops.

I'm sure there are certain things in Survival mode that would be "Speedrun-able", but I would be more interested in the high round of it such as in Zombies. ZWRs has a list of the high round Survival WRs. - https://zombiesworldrecords.com/leaderboards/mw3/high-round-survival
