It would be only possible if the two characters definitely need each other, I think for example of Frankenstein and his creature. And I think a Dullahan would have trouble fitting in a crowd wouldn't he?

The dullahan and his handler are part of a circus/freakshow display as the 'headless couple'...involves the woman wearing a glass box in the far back of a white room as part of an optical illusion, while her dullahan is commanded to interact with the crowd much closer up...or something.
