Here's where I'm at with Oriusburg:
Did some remodeling last night, and replaced my Archdruid's Hut with another Hero Tavern. Also removed the Celtic Farmstead, an old Checkmate Square and a Timeless Dojo and added the Sunhaven Palace, a Jester's Stage, Golden Goal Gyros, and the new autumn building. That boosted my attack by about 30% on everything but red defense IIRC. Didn't need the coin boost or coin rush from the druid and I just used them for AD fodder. The Buccaneer's Bay makes a coin boost anyway. I should probably remove the old Sundial Spires and the Winter Spire, but I need to add something that at least equals their combat boosts which are all blue defense IIRC. Maybe prune out the Carousels too.
I want to get in the new SAT GBs and I think I'm going to replace my Babel with the Hydra. I don't like ripping up GBs, but the Babel isn't really doing anything useful anymore. The RAH and maybe Inno Tower might get removed too. I might use the other two SAT gates to replace the Fire Pagodas.
I got a lot of empty space there at the bottom of the city but I don't want to add any more until FE. I plan to add the Space Carrier and A.I. Core once I hit AF, and the Blue Galaxy should probably go in soon too. But I don't want to have to rearrange things again too soon.
