You could, but it would need to be in the battery compartment, which the OP wanted to avoid. And once you're in the battery compartment the isolator doesn't add much in the way of convenience.
Ah... unless you ran a longer negative cable into the boot somewhere so that you could fit an isolator inline. Then you could just open the boot to access the isolator... provided nothing could accidentally trip the isolator whilst driving!
