It would change the entire dynamic of the show. Plain and clear.
I'm all for color-blind casting - when it's appropriate, like with the following shows:
Peter Pan
Carousel
State Fair
A Funny thing Happened on the Way to the Forum
42nd Street
Blood Brothers
Cats
Follies
Into the Woods
Kiss Me, Kate
Les Miserables
Song and Dance
Titanic (other than the real people)
Company
City of Angels
Chicago
Steel Pier
The Secret Garden (to an extent)
It is NOT acceptable in shows like:
South Pacific
The King and I
The Sound of Music
Flower Drum Song
Aida
Big River
Bye Bye Birdie (to an extent)
Cabaret
A Chorus Line
Evita (to an extent)
Pacific Overtures
Caroline, or Change
THE LIGHT IN THE PIAZZA
