Before I post this, I should mention that I am by no means an artist. However, I did grab a pencil and paper and sketched out quickly what was in my mind after I read the book. I don't have a scanner nearby, so the best I could do was take picture with my phone. These are just my initial thoughts about the station, try not to focus on the fact that my drawing is awful!
Also, I should say that I was quite delighted that the USS Rio Grande actually outlived Deep Space Nine herself!
Well, try not to laugh too hard, but here it is: http://i.imgur.com/GYwUs.jpg
I like it! Not bad at all.

However,
it does still show the Wormhole, which is anachronistic in any drawing of the new DS9 (so far as we know) 

Not bad, but I think the book said that the three rings were all mutually perpendicular, so that inner ring should be rotated 90 degrees clockwise (or counterclockwise). And there should probably be more crossover bridges between rings.
I've had trouble envisioning what DRGIII meant when he said that the 3 rings were all mutually perpendicular, and I admit that I'm still flummoxed by it here.

I agree about the crossover bridges, though.
