Halloween themed event idea

Ok. I legit made a Reddit account just to post this in hopes that people like it, and if so, someone in development sees it. Here’s the premise. It’s a 3 v 5 match with a 10-15 min time limit. 3 zombies versus 5 heroes, to start. The zombies have lowered health but they get life steal. If a hero dies, they come back on the other team as a zombie. So a 3v5 can quickly turn into a 4v4 or 5v3 etc etc, hence the time limit. The whole goal is, turn the opposing team to zombies OR survive for that 10 minutes until a “cure” gets distributed. The cure idea is just there for story. I can’t imagine they could make all that in the, less than, 2 months before Halloween but, that would give us a whole mess of new skins and a new battle mode for next year. Thoughts? Concerns?
