Yes, you can request a new set of medals from the NPRC. It "should" come with a V device, then.
Remember, the government didn't actively track down every valorous Bronze Star recipient and send out a V device for their ribbons and medals. If Don would have gotten a new set of ribbons after December 1945 he should have gotten a BS ribbon with a V.
The wearing of the V became a badge of honor, distinguishing the combat award from the administrative or meritorious award. You may remember the case of Admiral Jeremy "Mike" Boorda, Chief of Naval Operations, who committed suicide in 1996 just before Newsweek magazine reporters attempted to interview him regarding wearing V devices on his ribbons that weren't authorized.
