I picked up 75283 AAT, mainly for the minifigs, but I put the AAT together and it’s not bad IMO with a couple of very minor mods - I took out the larger diameter parts of the main gun, flipped the side guns so they are the correct way up, and removed the round part between the hull and the cones pieces that hold the side guns. I may look to make the turret narrower, but I may have to sacrifice the seating for the droid up there.
