Fighting game spin-off concept

I want to see a fighting game version of the champions in the style of pokken tournaments battle style but in a 4v4 (or 5v5) aspect in this big stage. No minions or towers. Just fight till you knock them out. But here's the catch. Just like in normal league you have a timer once you get KO'd and the match lasts five minutes. The team with the most knockouts wins. Arena's vary b/w every region in league and some of the lands in skin splash arts. Ex.: the pool party skin's. Takes place on a tropical island beach and has other champions and/or creatures/humans spectating them. Roster would be:

1. Ahri the nine-tailed fox
2. Akali the fist of shadow
3. gnar the missing link
4. Ekko the boy who shattered time
5. Fizz the tidal prankster
6. Vi the piltover enforcer
7. Tryndamere the barbarian king
8. Yasuo the unforgiven
9. Udyr the spirit walker
10. Taliyah the stoneweaver
11. Warwick the wrath of zaun
12. Taric the shield of valoran
13. Zed the master of shadows
14. Xin Zhao the seneschal of demacia
15. Sion the undead juggernaut
16. Olaf the berserker
17. Master You the wuju bladesmen
18. Katarina the sinister blade
19. Kayn the shadow reaper/ darkin scythe/ shadow assassin
20. Kled the cantankerous cavalier
21. Lee Sin the blind monk
22. Irelia the will of the blades (rework)
23. Anivia the cryophoenix
24. Annie the pyromancer
25. Diana the celestial aspect of the moon
26. Darius the hand of noxus
27. Poppy the keeper of the hammer
28. Ornn the fire below the mountain
29. Xayah the rebel
30. Trundle the troll king
31. Volibear the Thunder's roar
32. Fiora the grand duelist
33. gangplank the saltwater scourge
34. Rakan the charmer
35. Riven the exile
36. Kindred the eternal hunters

DLC champions:

1. Galio the colossal
2. Azir the emperor of the sands
3. jarvan lV the exemplar of demacia
4. Camille the steel shadow
5. Jax the grandmaster at arm's
6. Nasus the curator of the sands
7. Renekton the butcher of the sands
8. Garen the might of demacia
9. Wukong the monkey king
10. Kai'sa the daughter of the void
11. Leona the celestial aspect of the sun
12. Miss Fortune the Bounty Hunter
13. Shyvana the half dragon
14. Aurelion sol the star forger
15. Zoe the aspect of twilight

It would be simple. With a free-for-all 1v1v1v1 game mode, tournament mode, story mode, and a online mode.

Let me know what you think about this idea of a spin-off game. <3
