I've thought of this a few times as well but have never really followed up on it. The problem with most generic remote mount kits is that they are for the old style Ford filter (Motorcraft FL-1) which has different threads than the filter the Duratec uses (Motorcraft FL-820S). The FL-820S uses metric threads.
Other models in the Ford line up that use FL-820S filters that have factory remote mounted oil filters include some Expeditions and Navagators. Perhaps some parts from one of them could be used to move the filter on a Duratec. It might be difficult to keep everything far enough away from the exhaust manifold though.
