Yes, this would work. It's usually considered bad practice to define functions inside other functions, because it can lead to confusing results & poor performance -- but it's okay to do.
It can also be considered useful since it hides the functions from other contexts.
A warning: Defining functions is very slow. While it's not a problem for something like PlayerAdded, since it will happen at most a few times a minute, if it's something happening a lot -- it's better to reformat to avoid that.
A PlayerAdded
even without the parameter isn't very useful, don't forget it
