you can use shims on the carpet side to level the tank. Otherwise you take the chance of damaging the stand and/or tank because it will begin to sink on the carpet side but not on the tile side (you might even damage the tile b/c of the weight). Try a test run by just filling the tank with a hose and tapping in shims under the carpet side to keep it level while filling. Lay level across the top and tap in shims along the bottom. When it's full of water and level just cut off the shims. It might sink a little more with gravel and rock but you can just tap the shims further in to adjust. When your done cut any exposed shims off with a utility knife. Nice tank.

Too bad it wasn't reef ready....
I saw a tank that had two overflows on the back side in the same position like yours. They used one of the return lines in one overflow to run electrical up to their canopy, allowing the wires to be hidden...
My 2 cents... something to consider is how much scraping and glass cleaning you want/intend to do. With that placement, you almost certainly would have to scrape front and back glass for viewing, and probably both sides as well.
We, and I think others would agree leave the back glass unscraped, so that algea can grow there as food for critters without being really unsightly. With the tank in the middle like that, it would require some serious upkeep (or major snail cleanup crew) to maintain it.
Just my 2 cents...
