What is actually missing from there?
The only way to do this would be to first figure out the differences between the LDU and the chinese copy. It can be done BUT IS VERY VERY DIFFICULT. You're going to have to use oscilloscopes and go through data sheet upon data sheet to really figure out the the circuitry before you can begin making the other parts work with the LDU, after which it probably won't fit back into the case. There is much reverse engineering to be done, because the chinese manufacturers probably don't use the same design templates. (The Kobo Glo and the Tolino eReaders use the same design templates. Have a look at those boards for a better idea)
If you do manage to use genuine S5 parts in the LDU, I'd like to learn more.
Remember, anything is possible.
