I truly don't see Animation Studio mimicking that front page to be honest. I know you can do some cool things with that program, but replacing an entirely flash page animation setup is beyond it's capabilities without the person using it having extremely good graphics capabilities to work with.
Basically that program works with a series of frames that create an animation similar to the old paper tablet method with a different image in a different pose on every corner of the page type setup. yes you could probably attempt it, but you'd have to do some really good stuff with timing of every single animation image which would have to be every section separately. Menu items each their own image, everything pretty much it's own image and done in dozens of poses to create one part of it. Then you'd have to get the timing of every single image (every frame for every single image) so that it's done to the right timing so all things work together. I can see something like this taking a very long time (weeks to months, most likely months) to create.
You would be better off looking into some java-script or jQuery setups and losing the full animated page system and just animate portions of it. Just my opinion of course, which doesn't mount to "a hill of beans" hahaha, but thought I'd chime in that it would be a really extreme amount of work to try to do that in Animation Studio.
