I just use pictures like that for insipiration - to pick up design tips and the general theme of the map.
With Mayan architecture, it's generally all steps, terraces and 45 degree angles. No need for bothersome patches! No need for direct translation - in your case, you're building a fort that the rebels have constructed, so it wouldn't have to be like the Massassi temples, but I would assume that they would be sympathetic to the surrounding enviroment. Just add little bits here and there to tell players that they are on Yavin and not just in rebel base X.
Also, if you can find some close ups of the wall engravings, you can fiddle with them in Photoshop (or your preferred texture editor) and import them into radiant - give your map a bit of Mayan (Yavin) flava!
