Yes this is still in the design stage, I have volunteered my G68 to be the trial unit.
Once we have confirmed there is enough interest, I will get a prototype unit to fit to my G68 and assess.

I'm very hopeful this will give a large improvement over the stock power supply, and also a big improvement over the LM317 type Linear PSU's that people have been trying.
