Hey, Jax, if you want a planet in my map, go right ahead and make one. I will include any submitted candidate as long as they meet the requirements, i.e. looking "realistic" and fitting in with the general style of the other planets. I'll even let you name it if you want!

And I might look at that GURPS thing. I was originally going to include short-ish description boxes for each planet. As I progressed I could see that simply wasn't possible. I also do a bit of writing, so I'm thinking about making a small companion book, where each planet gets a detailed description, including climate, population, industry, special characteristics, etc.. It could also feature small thumbnails with each planet. If I can find time for all of this, of course.
