I think 48/72 hours is in-practical - I would guess that the most common legitimate reasons for disabling Find my iPhone is either 1) to sell the phone 2) To get it repaired by apple.

Asking these people to wait two days before they can get their phone fixed or to sell it wouldn't be a nice user experience. Can you imagine the amount of pissed off people in the Apple store waiting to get their screen fixed only to be told to come back in 2 days?

1-2 hours would be the ideal candidate I think without being a inconvenience.

Another idea would be a 24-48 hour window to 'revoke' the disabling of the activation lock. Perhaps they can login to Apple ID website to reinstate activation lock remotely.
