This is not a viable idea. The backlight sheet from an ipad is intended to shine a bright light through an LCD panel. An E-Ink screen is opaque. The front light on an E-Ink screen has very clever optical properties to reflect an even low light onto the E-Ink screen, which then reflects off the screen, back through the frontlight layer and makes the screen light up.

Even getting electrical connections to the LEDs is going to be hard - LED driver electronics has to cope with the way the LED resistance changes as the LED warms up - just connecting to the +ve voltage available in a kindle is unlikely to lead to a happy result. Let alone give you an adjustable light.

Seriously - save up for a new eReader with a front light. Don't waste your money on this project which has no chance of success. UNLESS you're doing it for the fun of tinkering, not to get a working lit ereader.
