I actually considered it. I had originally planned to add not only the MC castle tiles, but the FSA tiles as well. The tileset is massive already, and adding them in might require a little bit of relocating of some tiles and resizing the canvas for the tileset. I was also planning to add in all the custom parallel worlds tiles, but I figured that it was best if just a few of those made it in. After all, there is a TON of variety already just in the current tileset. I will give it a lot of thought though (But my mind is already leaning towards yes xD)
