That will obviously require some work ...
I'd start out learning about
Away3D[
^] and
Spas[
^]
I'd use
FlashDevelop[
^] and
Adobe Flex[
^] to develop the application, as I think a pure ActionScript approach will allow you to get the job done faster.
The resulting swf can be included in a "master" flash project, and you can use existing assets as part of your application.
