Actually, Oz, all of those buildings (except the mid easter Yevon Temple and the mesoamerican Maester tower) have already been released in some form or other... You'll have to dig through the "Building and Wonder Graphics" sticky thread in the graphics modpacks subforum...
If you could list the ones you need, I could point you to where to download them or release them separately.... If you're after the Fire Shrine and such, I was planning on releaseing them soon enough.
Oh, I've also started on a unit (yeah, I know, I should finish Razfahd first and spend more time looking for graphics for the various summon small wonders)... I'm making Ultima (the World of Ivalice civs' summoned creature), based on her Final Fantasy Tactics appearance... Essentially, she'll be in the form of Alma during the default, run and fidget animations, and transform into Ultima during the fortify, and be in Ulitma form for attacks and the death animation... I'll post preview pics when I get the textures for her outfit worked out. (and download Kinboat's Angel Wings... I seem to have forgotten to earlier)
