I'm not accepting. This will be a very long script/tutorial that take several hours, maybe more than 10 hours! Besides I have no interest in such script. If you like I can give you some tips, but nothing that takes me too much time.
1. I guess that you only need to change the coordinates of the content, right? If you have problems I can point you the right places.
2. This fills better on Pokédex, isn't? Anyway, making changes on summary need that you change all summary pages for replacing the page icons, isn't a easy task. Pokédex have the same problem, but there are less pages. I suggest you looking into Family Tree about how adding summary pages and Advanced Pokédex about how adding pokédex pages.
I would send you the script if it worked, but I'm still working out the kinks. It's an edit that has to be made in multiple scripts and it might be affecting the way my Trainers work, so there's still some hammering out to do.

Ex top of a tree on a route would be up, after activating it passes perspective on top
