Wet blanket time:
Except for Andrew Lloyd Webber there is not a star name attached to The Woman in White nor is the source novel part of the US literary history.
Maria Friedman, Michael Ball and Judy Kuhn all mean something to us, but to the Great Out There that is the USA, no one has heard of them nor have they heard of the show that could only squeeze out a 3 month run in New York. The show by itself will not sell.
Forget ruminating on which original cast members could go on the road and think of a BIG star (or two or three) who would sell tickets.
What TV series has gone off the air in the last 3 years with a star who could do one of the leads? This is the question that ought to be asked.
