I think its a great idea to switch to a synthetic oil, if for no other reason to be able to go longer between changes. However, I'd suggest skipping the Royal Purple. UOA's (used oil analysis) have shown that Royal Purple has a tendency to quickly shear to a lower weight (ex. 5w-30 to a 5w-20), which is not a situation you would want to be in. I would suggest that you consider Mobil 1, Pennzoil Platinum, or Amsoil and stick with the Motorcraft FL820s oil filter. The Motorcraft oil filter has the Ford preferred location of the bypass valve (threaded base of the filter), most others (Wix, Mobil 1, Pure One, etc.) do not.
