Are there any privately owned V-22 Ospreys? Could someone buy a V-22 Osprey and convert it to a luxury interior rather than a military one? Has anyone done that? Are there any images available of a private Osprey made to be luxurious inside? What does the interior of the US President's Osprey look like?
There are no 'private' Ospreys thus far (all are operated by USAF, USMC and JSDF)- the Bell Boeing MV-22 Osprey used by the US Marine Corps's HMX-1 presidential helicopter squadron:


  ... will conduct presidential support missions, which means these aircraft will carry presidential support staff and news media representatives travelling with the president," the USMC says. "The Osprey mission at HMX-1 does not include carrying the President of the United States."


so I'm not counting on 'luxury' interiors. When (and if) a civil version of V-22 is produced (or if the Japanese feel like selling theirs), you can buy it and make the interior whichever way you like.
