First, welcome! You sound like you've been to some serious electronical schools... :O
The idea has been discussed many times, but it was long time ago and mostly on MoMo...We all know MoMo is gone and so is all that knowledge...
If I remember good, best idea on MoMo was to replace the part that tells the proccesor on which speed to run or something like that! Im really no good with that technical stuff...
I would like to wish you luck! Anything you need - ask for it
We would all love to see that happen
BTW, you gonna edit the firmware? Woo coool, you know ASM?
*edit* I just noticed that its a picture of a Neptune LTS not LTE ?
