One approach that sort-of works is to plug two walwarts (one for the  Pi,
one for the hub) into a single 3-outlet extension cord, then coil  the
excess wire (both mains and 5-volt) around the cleat- like object  which
results and hold it in place by a cable tie or split conduit.  I've done
a couple like this and it's ugly but better than loose  wires. One can at
least see where each Pi plugs in.

 
I would be careful -> avoid coiling low voltage with high voltage mains.
 My concern is that you would end up with something akin to a (poor)
transformer of sorts.  Wherein the high voltage mains would couple onto
the low voltage lines.  At a 1:1 ratio, you'd end up with the same high
voltage on the low voltage secondary side.
 
I don't know how many loops on a coil would be needed for this to be
noticeable.

The mains cable has the live and return together all the way, twisted,
so the field cancels out.  The transformer effect will never become
noticeable, no matter how many turns.
