is there a way to split swf files generated using unity

Hi All, I have to upload a swf of my application but its size is almost thrice of what i expected. Now I don’t want to increase the loading time for the user, Is there a way I could tackle this situation, may b by splitting the swfs? if yes then how? thanks in advance

Can use a flash native application to load the unity swf and then access functions on unity swf from the native flash swf??
