Ethel Merman toured in CALL ME MADAM in the 1960s. But she also revived ANNIE GET YOUR GUN on Broadway, which is a better example, I think.
If you count tours, the list will be almost endless. Before theaters were air conditioned, it was quite common to take the Broadway company on tour for the summer and then return to Broadway in the fall.
To take a different type of example, George Lee Andrews understudied Len Cariou in the original A LITTLE NIGHT MUSIC. Then George took over the role permanently in the national tour. Assuming he went on for Carious at least once, then he "returned" to the role on tour.
Meanwhile Hermoine Gingold played Madame Armfeldt on Broadway, gave way to Margaret Hamilton for the national tour, but took the role back for the last three weeks in Fort Lauderdale. She did so to brush up before her appearance in the London production which followed the tour. (Trivia: Miss Hamilton sent the company the most gracious good luck note, despite having been left behind in Boston!)
For all these reasons, I think we might restrict ourselves to "returns" on Broadway.
