Hi Craig,
Very interesting. Off the top of my head a Surrender 'Sally' was preserved by the Australian War Memorial, before being scrapped in an ill-guided rationalisation in 1956.
The history of that aircraft is reasonably well documented. See:

From the records thrown up by the search on 'surrender' and 'sally';

A Japanese Mitsubishi Ki-21, Army Type 97 heavy bomber, allied code name "Sally", leading a Nakajima Ki-49, Army Type 100 heavy bomber, allied code name "Helen", off the Pitoe airstrip. Both aircraft are carrying some of the staff of the commander of the Second Japanese Army Lieutenant General Fusataro Teshima. As the Japanese were short of serviceable aircraft General Teshima arrived from Pinrang in an RAAF C47 that same day to surrender the Japanese Second Army to General Sir Thomas Blamey. The aircraft have been painted white and carry green crosses, denoting that they carry surrender emissaries. (Donor C. Freeman)

This aircraft was probably the Sally which was flown to Australia in February 1946, having been nicknamed Tokyo Rose.The Tachikawa Ki.54 transport aircraft (Allied code name 'Hickory') (right) has also been painted white and its hinomoru marking has been transformed with a white surrender cross. The Hickory was used to fly Lieutenant General Masao Baba, Commander of the Japanese 37th Army and Supreme Commander of the Japanese Forces in Borneo to surrender at Labuan.
