Quoting Kaitak (Thread starter): Does the conversion of a 744 pax aircraft to a BCF include the installation of a hinged nose - or upward opening nose door - whatever is the correct terminology, (as on standard 747 freighters?)
Have any 747s ever been modified to add the upward opening cargo door after the aircraft was built? I don't think so. That would be a huge job and very expensive.

I don't think so. All 747s that were converted to freighters only got the side cargo door (if they were full PAX aircraft and not combi) and the usual stuff that goes along for conversion like floor strenghening, deactivating doors that aren't required anymore, and window plugging.
Perhaps the only exception of sorts is the 747-200C, which is mostly being operated by MP. Those are quickchange aircraft which were basically the freighter airframe (with the nose cargo door), but with provisions for use as passenger aircraft. MP hasn't operated those as PAX aircraft since 2002, but they could in theory be put to PAX service when required, and later be changed to freighter configuration.
