Nice, You have discovered Scheimpflug rule. My first enlarger I've bought back in 70-s was able to apply it - and it was really fun to do some experiments with it.

But time goes. Sorry, but focus stacking is in many cases is simply better than tilt function. Also, on location, it's faster than fiddling with tilt angles - if You want to get the best from the image. And it's free, with every Photoshop. Also with some free software.
