Sorry to pour cold water on your idea, mate.
But the question does beg asking, even if those cables are carrying relatively low currents, do they heat up to some extent?.
Given that they are so tightly bundled and all cables exhibit electrical resistance along thier length.
And it looks like those particular cables are running for a fair stretch!.
There's nothing like a neatly bundled and tied cable installation, though.
