first of all I want to make clear that I don't have anything against this project, I am discussing just my personal opinions and suggestions here. If you find it useful you are obviously free to do it the way you want
The idea of making Sabayon more accessible to non-technical users is an idea I also like, it is precisely why I find this project interesting, but having a Control Center which handles something and also having a desktop control center that handles the same thing is a redundancy, even if they don't share the same configuration files. It is actually worse not sharing them, since they will most likely conflict each other making the system more unstable and disorienting a user who won't be able to understand which tool he is supposed to use.
In my opinion there are utilities that would deserve a GUI in Sabayon which are not handled (and will not ever be handled) by Desktop specific control centers, like rc-update, eselect, LiveUSB creation, packages snapshots, BTRFS snapshots and so on, a control center that offers a GUI for such utilities would be extremely useful.
On the other hand duplicating an already existing effort is useless in my opinion, for 3 reasons:
1) the desktop specific utility will most likely do the same thing better, since it integrates itself with the desktop.
2) you know exactly that you are supposed to use that utility, no conflicts will arise, if something is wrong you know where you are supposed to look.
3) the developers can focus on utilities that are not yet available, spending their development time better.
