I can't say very well that I can proceed with the coding for your request :/
Guess I have to let you down, cuz` there are many other things to do and I simply can't find the time when I'm gonna do your request.
Perhaps you will have to find another coder, sorry :/

I put the sounds i used in there too, you will have to experiment yourself as to what paths you are to overwrite them with etc. Just check the event objects of the models in magos and you will see the name of the sound.
