Make names from old accounts available

If an account has been inactive for 3 or more years, I say we make their name available. First come first serve kind of deal, whoever attempts to change their name to the inactive account's name first gets it, and the original account gets a name that replicates it as close as possible (if the name was "Microwave", they become "Microwave1", something like that.) The owner could also "lock" the name or something? An option to keep your name unavailable to others, something along those lines. The account's getting no use out of it, I don't see a reason why nobody active can.
