This is a great idea (and thank you, @SharktasticA, for your dedication of time and effort towards documenting all these multifarious keyboards)! I’ve been thinking lately it ought to be possible to generate these directly from KLE data (in fact it would make a nice feature to add on to KLE itself to show icons of layouts in the picker).
Parse the KLE data, along with a few more optional settings for color, etc. and boom! Automagic keyboard pixel icons!
