Regulating how people maneuver during repops or in general isn't a plausible idea imo. Whatever agreement is reached, it needs to be relatively simple and easy to implement and control. If the alt rule is breached in your proposed scenario, then GMs would be sifting through IP addresses and alt names for hours in order to punish the rule breakers.

Personally I feel like the easiest answer to this problem would be to repop mobs randomly every week or so, and prevent them from repopping at any other time. It would spread the loot without having to track or have people training/stalling/etc. But it is not classic at all.
