I'm not even sure what an ISO layout would even mean here? This keyboard is otholinear, and already deviates fairly meaningfully from the normal US layout. It is mising 5 keys from the core typing area, and only adds back 3 of them in the extra row with arrow keys. So you already need to utilize the extra new buttons for some of this, in addition to space bar, modifier keys, layer/mode control keys, etc. People who buy these types of keyboards often create very customized layouts to handle things like convenient macros, buttons not physcially included on the keyboard etc. ISO users could do the same. For example, moving shift buttons down to the thumb area gives you a place for the extra ISO key in that row. The missing extra key from in the home row could be moved to say the key between return and backspace. Or return could be remapped entirely, or whatever. It is really very unclear to me what an ISO variation of this would even be.
