Pokemon Reborn Roll20 Maps?

[Slognosticator]

Hello to anyone reading! I want to preface this by saying I love Pokemon Reborn, as most people on this forum would (I assume). My love for this game has set me on a journey to expose this world to as many of my friends as possible, through any means necessary. Therefore, I have created a Roll20 D&D campaign for the story and world of this game using Pokemon Tabletop United! I do plan on giving credit where credit is due for the creators, as my friends know nothing of this game, they only know the Pokemon mainline series. 

 

As I search the wiki, I see that most of the maps are there for me to convert into a png format. For example, for the Lower Peridot Ward, I just download the picture of the map, convert it into a .png, and input that into Roll20 and set it as the map layer. However, I've run into a small dilemma. There are a few maps, especially for inside buildings, that do not have maps on the wiki. For example, I am looking for a map of inside the Grand Hall so I can do the previously mentioned conversion to .png into a map layer on Roll20, but I cannot seem to find one. All I have found are small bits and pieces of the inside that do not complete the puzzle that is a full map of the Grand Hall interior. I understand that the Reborn Wiki is still being edited to this very day for recently updated content for Episode 19, but I must ask; is there a way to find such maps in a completed state, or will I have to create them with the tilesets that are provided in the game files/try to describe certain areas without a map?

If you have read thus far, I hope my request makes the least bit of sense, and I thank you for your patience and help in my journey to host my friends on the adventure through the Reborn region.

TL;DR, I want maps for a Pokemon DND campaign based on Reborn, but certain ones are not available on the wiki (i.e., Grand Hall, most buildings, etc.). Just wondering if there's a way to get them or I have to make them myself.
