Using both AS 2.0 and 3.0 files?

I have a designed an entire Flash site using AS 2.0/CS3 but a friend recently turned me on to this great video player script written in 3.0, which I need to incorporate into this website.
My idea was to design a single “video” page in AS 3.0, save it as a seperate swf and then link to it from the main 2.0 site using ‘getURL _self’ in the navigation menu.
Assuming that this would work, my only issue would be how users would navigate back to the main 2.0 site. I am using frame labels to navigate the main site. Could I somehow use a getURL script in the 3.0 video page to go back to the main 2.0 swf AND define which frame label I want the 2.0 swf to load (depending on which navigation button the user presses)?
Thanks for the help.
