I've looked into how the game loads warpzones before. When a warpzone is loaded, it doesn't just increment the value. It runs a section of code that determins what that number should be. It goes something along the line of "if you're in world 1, load the first warpzone. Else if the palette is above ground, load the second. Else load the third." Even if you could load the warpzone multiple times, it would still be the same. Interesting idea though.
