Sorry, but I veto that!
Seriously, all that is just draining resources, Because of the crowd and stadiums being more detailed the RAM (and graphic card too) requirements had a noticeable jump from FM11 to FM12. And such requirements would be greatly increased by something that's just tertiary to the game. It's an strategic game, anything graphic or sound is just lollipop. And it could easily be resources taken for other more relevant tasks like improving flexibility of tactics to introduce new kind of instructions to make tactics more like reality, as the increased processing power required by that would be used in non-relevant graphics sounds for this product.
Maybe the improving of sounds can be done with far less drainage of resources than graphics, though.
