Nope, otherwise it would have been done. There exists the pre-release MF1 Odin package for when someone screws up, but the only way to get MF3 back (which doesn't have any other noticeable difference other than being able to actually OTA updates) is going to a Samsung kiosk and convince them to load it on your phone (see some of the other threads here about how to do that, which I contributed to as I did it as well).
