GOTCHA!!!! I'm so happy, it was a very interesting (exhausting though) experiment, I've learned a lot :)
Useful information to build Kernel Package are [1] and [2]. There is still shenanigans in my process, I do not get yet how to build my own meta-package (I use Ricardo's one), how to properly track modification / changelog, and use my PPA. So I do not feel comfortable enough to write a documentation about the process, but in case it is interesting for the community, with some help to guide me, I will do it with pleasure.
