This kind of stuff is SIGNIFICANTLY more alluring when you're dealing with an air gapped pc.
Interdict the mouse and modify it so that it uses the needed software over usb, pair with a Software Defined Radio device and a specially modified usb plug to exfiltrate any data picked up, the user is none the wiser, you've grabbed whatever info you're after, and you never even need to physically access the air gapped pc.
It's elaborate but if you're targeting an air gapped pc or network then elaborate is necessarily going to be the name of the game.
If you introduce specially modified hardware, why not just add a microphone?
If you're looking for something amiss you'd notice a microphone. Unless you really, really, really knew your shit something like this could be essentially invisible even if you disassembled it.
