That would work in case you have the phone unlocked (in the sense of PIN already entered and not related to bootloader). Still if it is locked, you shouldn't be able to upload anything via adb. I guess one possibility would be to install one of those pin unlock apps (which do not require root) and reboot, still that would require the google play account and the phone being connected to the internet at that time. But yes, that makes sense for PIN recovery - then you can root the phone and proceed.
BTW is there some screen lock bypass trick for Samsung S3 ? I've seen such from time to time...not for s3 as far as I remember...
