Think your misunderstanding me :-)
What I mean is, as a comparison...
You can upgrade officially via kies, doing so does not wipe your phone, does not factory reset or anything else, it merely upgrades the firmware etc.
Now If the op wants to get rid of his chosen custom recovery and install stock recovery, he can do so by flashing a stock Rom via Odin, doing so will restore stock recovery and everything else done during an upgrade over kies, this will not delete any apps or any other data :-)
