Ok I just spent until now, trying decompiling and recompiling properly SystemUI.apk. I understood many interesting things browsing xda board and google to check why I always get many errors. And I conclude that, stangely with XWLP8 base WanamLite ICS ROM it does work, but which was not the case of his XWLP9. So the problem is if I want to get it working, for this moment it will be only for LP8 and nothing else, where I really want to make it working on every firmwares. I guess that there is some problem with latest wanam LP9 framework-res/twframework-res/lidroid-res and SystemUI APK's release, I don't know.
I hope for a futur apktool release which will be more flexible about ICS modding
but latest release was december last 2011...
So, for now, no transparent toggle, sorry
