[DISCUSSION] Creating Ultimate KDZ file. - LG Optimus L9 P760, P765, P768, P769

Its really a pain for Jimmy(Our average power User) to read all the instructions for root, then for unlocking,then upgrading,then for CWM.
I want to make all this process is easy as flashing a KDZ only.
I want to create a Ulitimate KDZ file with these features,
Rooted Jelly bean 4.1.2
Unlocked bootloader
CWM
Now that we have unlocked bootloader on many P760.
It would be nice if someone could share dump their bootloaders and share with the L9 community.
I was thinking whether it was possible create a edited KDZ with unlocked bootloader and cwm built into it?
Is practically possible to make somethink like this??
while googling around i found this awesome tool
https://code.google.com/p/arenoid/wiki/KDZExtractPack
Is this tool relevant for the job what i intend to do?
I need suggestions from devs on this topic.
It would be helpful if someone could put some light on this topic.

I think this was tried before few months back by someone on ics with locked bootloader with no success. But as now bootloader is unlocked its worth a shot again. May be I will try this in a day or two when some extra more time.

just tried this tool : http://forum.xda-developers.com/showthread.php?t=2020737
not useful for L9.
Till now i've managed to Extract KDZ and then Pack with the tool in the first post.
Creating a rooted stock ROM seems easy. (thanks to lewis)
You just have to Extract KDZ << Hex edit Bin File << Pack KDZ back << Voila you got stock rooted rom.
But how do i include CWM and unlocked bootloader in it ???

I know spyrosk since long time/year and recently I am in conversation with him just yesterday for my rooting of ICS v30b rom two days back on Optimus 2x, which I still have. Yes he knows me from o2x forum
The tool is good here for various things but it is not for rebuilding kdz. We can only use it to extract KDZ but even I have my own simple way to exract kdz and working great for me.
Let us see what else can be done to rebuild kdz. May be someone else is already working quietly on this.

@cmahendra do you know any senior member who knows the procedure of rebuilding KDZ file?
we can take help from him maybe he can guide us in the right direction.

What about just pre-rooted rom? Could anybody handle it?
//edit: sorry for redundant question, i misunderstood posts above...

Have you managed to do all this for L9? How exactly?
I just wanted to Extarct KDZ file and pack it again to achieve the same KDZ file binary equal to original).
I tried with V20C_00.kdz
Decrypt KDZ file generates one WDB and one DLL file.
KP500-Utils-EN.exe doesn't accept this DLL file
Choice: h
Location of DLL (Ex C:\Inf_WebDnld.dll): LGP760.dll
Procedure not found:_StartUpgrade

I have used LGExtract.exe which extracted several BIN files from WDB and LGP760_CP.fls. To merge those files into KDZ I had to create .txt file with file list and merge order. After merge I have KDZ file again but it is few kB larger than the original.
