Question [Q] Can I update to 4.3 manually without overwriting /system

I'm currently on 4.2.2 on a locked bootloader & I've managed to create an ftf (of both 4.2.2 & 4.3) using the guides. I don't want to unlock the boot loader as I prefer to stick with the stock rom & only root.

I'm sorry if this is stupid / wrong way to go about thing but Is this possible ?

1) I update all the partitions except /system using flashtool.
2) since I have root, Mount /system on my phone as rw.
3) extract /system from the 4.3 ftf and push the entire content of system manually (keeping root in the process)
4) Reboot ?

Is this possible ?

I'm sure this procedure needs to be fine tuned as I'm sure the permissions of the files pushed might be wrong.

Any help / tips ?
