So lets say I have a brand new account that has a name I like. Is it possible to change my name to that account? Alternatively, would it be easier for me to just request a name change?
Or do I need to be a Donator to change my name?
its difficult to say that it would be easy to change your username, the only right person you would ask is theymos no other than him.
and yes you need to be a donator to grand what you wishing for, because like minifrij said,
without a Donator tag there is not a 100% chance that it will be granted. so you have to be a donator first before to request to change your username at first place.
