Create dynamic crowd effect

Hello, my name is Jan and I lead development of fantasy browser game Kornhal. We are looking for sound engineer who is able to create crowd effects for mid-size arena like in Gladiator movie. We need to offer solution and create the effects. It needs to have basic loop and then events based on actions in game.

We can study this scene from Gladiator movie:

My suggestion:
1) "Battle starts cheer" (https://youtu.be/Y7KD9CM_PjM?t=28)
2) "Nothing is happening" (https://youtu.be/Y7KD9CM_PjM?t=78)
3) "Slight hit v1" (https://youtu.be/Y7KD9CM_PjM?t=57) + "Slight hit v2" (https://youtu.be/Y7KD9CM_PjM?t=75), more examples: (https://youtu.be/Y7KD9CM_PjM?t=106), (https://youtu.be/Y7KD9CM_PjM?t=84), (https://youtu.be/Y7KD9CM_PjM?t=102),
4) "Clapping" - might play simultaneously with "Nothing is happening" for example
5) "Laughing" - might play simultaneously with "Nothing is happening" for example (https://youtu.be/Y7KD9CM_PjM?t=189)
6) "Big hit" - (https://youtu.be/Y7KD9CM_PjM?t=140)
7) "Near end" when some player is low on health (https://youtu.be/Y7KD9CM_PjM?t=159), will replace "Nothing is happening"
8) "Chanting" - can occasionally play during "Near end" (https://youtu.be/Y7KD9CM_PjM?t=199)
