I have done a few parts more then once . It was because I loved the roles so much . You are right it is different with different actors ( even with some the same in some of my cases ) and though I would do them again and I had still fun the second ( or third) time around , the experience RARELY equals the original . Though with more time in between maybe . Though also of note they all have been comedies for me , so maybe the "discovery" aspect would be greater at least for me in a drama , I don't know . Don't rule it out until you've done it yourself , and see first hand

I chose "only certain roles," really meaning "under certain conditions."

I've performed the same play, but in different roles in defferent theatres in different years.  Which really is fun and keeps things alive.  Each was so very fdifferent than the other.  I performed the role of Charles Dickens in a community Theatre production of A Christmas Carol and played four different parts in the Guthrie Theater's 20th anniversary production of the same play.

I've only reprised one role and even then it was as favor to a director.   Very few roles that I'd consider repeating, maybe Oscar in the Odd Couple (though I don't know if I could remember that much dialog ever in my life again) and Louie in Lost In Yonkers.
