Thanks. Is there a way to contact you via email? I have converted the wall tiles to 47-tile format too -- but they don't look correct (or maybe I'm not used to reading them). I'm not sure if these are in the 'free demo' so I'd prefer to email you directly instead of posting them here.

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!
