Good question.  Can it last that long?  Probably.  What do the food safety experts say?  Not no how, not no way!  But they are talking about purchased chicken with a posted expiration date. 
I'm not sure how long it will take it to freeze or thaw.  Some of that depend on how it is packed and if it in the same spot as the other two.
I think what I'd do is pack it fairly thin so it will freeze and thaw fairly rapidly.  Freeze it immediately without aging.  Then five days before you plan to cook it thaw it in your fridge an let it age in there after thawing. 
Food safety experts probably would not agree with this either but I typically take the meat out of the freezer on a Sunday to let it thaw and age before cooking it on a Thursday.  Never had a problem.
