There is no easy way to do this at the plus level. You would need to download the graphics individually, upload them to your home game and size appropriately, re-doing dynamic lighting, etc. With a Pro subscription, it is trivial. The Transmogrifier can move pages and other assets between games with ease. Modules are designed to be used in this manner. There is simply so much information that moving the entire contents into an established game would likely have a negative impact on performance. Moving things piecemeal is a pro perk. Some of the larger modules have the map packs as an addon. but I do not think this is so with OOTA. I think your two main options are to either up your subscription to Pro for a month, or to request a refund. or bite the bullet and do it all manually. Though I think your time is probably worth more than $5.
