Flash MX change large movie clip to separate swf's?

Hi all! My intro swif to a site is way too big. When using the bandwidth tester, it comes to a total halt for a VERY long time. The swf is currently almost 400k.

In the intro is a movieclip that is the big culprit for the most part. It has five pictures that fade in and out on separate layers. I wonder … these are right now staggered so that one layer with picture fades out as the next fades in.

Can I make these layers with pictures separate swf’s, and if I can…can I then put action to load sequentially these swf’s one at a time? would this work all inside a MOVIE CLIP?? Would this help get my movie started faster? These clips are masked on the main timeline, etc. I will gladly provide more info if my question isn’t clear. I need help with code
