iOS 7.1 Key Click Volume Control

I'm older (60 ish) and my hearing isn't quite what it used to be and with no sensory input from the keyboard, the key click sound helps a bit. But even with the volume control set to highest, it's still too low for my liking.

Is there any way to increase the maximum keyclick volume available?

I saw over on the iOS7 section a thread about a partial workaround utilizing the Settings > Sounds > Change with Buttons/Ringer & Alerts Slider combined with the Volume Controls kludge, but this still doesn't increase the key click volume to my liking.

Any ideas?
