You'll only be able to model the drivers separately, and that practically gets you back where you started.
Without factoring the cross-over and the driver locations in, all You're going to end with is a ballpark idea about the porting.
For a someone who's built cabinets, reverse-engineering the dimensions would be pretty easy, but since all the legwork is already been done, why bother?
