keyboard players tend not to worry about which inversions are playable on a guitar when they play the keyboard and normally stick in the same octave range for most chords as you probably know. Most don't worry about the composer either and just play what sounds right to them.

some keyboard players don't even keep in an instruments range on the right hand part so what hope do we have for inversions?

as mentioned before, the one thing that is better than having live guitar strumming on the Audya is a live guitarist sat next to you when you play the Audya. But the Audya provides a nice alternative in the absence of said guitarist.
