The auto tiles for the walls appear to be split in two parts:
"top of wall": 16x16, 16x16, 32x32
"bottom of wall": 32x32
Is this using that technique where each 16x16 "tile" is split into 4 "8x8" "corner tiles"; then the "8x8 corner tiles" are reconnected in different combinations to form "16x16 big tiles" to use ?

Is this a correct conversion? I used the tool at https://partyvaper.github.io/autotile-converter/ to do the "rpgmaker 3x2" to the "47 tile" format. If you feel this violates your copyright, I'll delete the output image (but not sure how to otherwise verify with you the output is "correct").
Oh, for the wall autotile, it will be weird and looks incorrect! This because unlike fences, RPG Maker technically treat a wall as vertical object and only span the full wall pattern horizontally. The upper part should comply with the 47-tile format though, but I don't think you will ever need that.
I will address this for the next update. Thanks for the feedback!
