Multiple swf loading using one loader suggestions

Hello everyone,

I would like to know if this method is correct for loading external swf files into the stage and navigate through them from buttons which are created dynamically:

So, firstly is it possible to load multiple swfs into one loader?
Then when a dynamic buttons is clicked navigate to the corresponding external swf by turning the other ones invisible and disabling mouseChildren so mouse events do not occur.

Would this be a memory killer? or it works like unloading swf files that are loaded on the stage by using unload(); ?

Thanks in advance :thumb:
