I would not ferry the airplane that far with or without a ferry permit. Two years of sitting and who knows what is going to happen? Who will be responsable if something goes wrong and you have to land halfway. Do you then call the owner and say that the airplane is broke and you left it in a field in california? The liablity is way too high. Why not fly your A&P to the airplane and have it inspected? Way cheaper in the long run and you are not out on a big limb...
Good Luck.
