Game Console Modifications and Hacking

I have a PS3 for quite a while now, and for years it worries me, the worst part to find replacements is the original controller. With very important functions being bound to the PS button, and my console being compatible to my knowledge only with HEN, the lack thereof would easily be a problem, and in my case, I'm already having to use the PS Move controller I have for PS button functions.

When I watched the video, I remember the thought crossing my mind: would this method help circumventing this issue?

Thanks in advance!
