I don't think Mr. Frid said he never wanted to play Barnabas again, even on occasion as a vampire, bu that he wanted to do more. Everyone else got to play other characters, yet he was Barnabas, Barnabas, Barnabas. Even David Selby got to play different "Quentins;" they all had the same name, but there were two others who were not his original character. In the 1840/41 storyline, Thayer David got to play - what? - forty, fifty different characters. In the 1897 plot he got to play two different ones; Grayson Hall got to play two (well, one was Julia); TLATKLS got to play two. One could even say that Nancy Barrett got to play two.
