Since you have no choice about altitude during an ILS approach,
adding kinetic energy is the only way to increase your glide range.

That's not really true. You can't go below the GS, but nothing says you
can't fly the entire approach above the GS.

You're allowed to descend below the GS as part of your normal excursions
(the FAR's call them bracketing maneuvers) to track the glide slope.
