Interesting.  If you do the shows well and establish your niche that could be a good way to stand out from the other theatres in your area.  The big challenge will be getting people in your door initially without shows they recognize.  But maybe you can get some good initial press coverage by being different.

Hope you make a few bucks with these chestnuts.  Sure it's great to revive some of these but you have to attract talent and audience, otherwise what's the point.   Not sure I'd go with an entire season of almost unknowns.  It's a risk that I hope pays off for you.

There is a small theatre group in this area (suburban Dallas, TX) that makes 'long forgotten' and 'off the beaten path' shows their purpose for existing.  They have been doing it for 10+ years with a somewhat modest, but very loyal audience because their shows are usually very high quality.  Check out Rover Dramawerks http://www.roverdramawerks.com/ and see for yourself.  I say there is definitely room for this type of theatre in a market chock full of 'mainstream' productions.  Good luck!  ...'Er, BREAK A LEG!

The Apple Tree is one of my all-time favorite plays!

6 big musicals in your first season, eh? I admire your energy and optimism!

We have Goodspeed Opera House here ( http://goodspeed.org ) which is dedicated solely to producing classic musicals. It's a first rate Equity theatre and have been successful for many many years. They also have another theatre where they do new unproduced musicals. It's where Annie, Man of La Mancha - among others - got started.

Go with your dream!

Thanks for all the responses.  I did spot that I left out we will be doing 4 of these 6 plays.  6 plays in a season would be pushing it for a new company.

I have discovered two additional problems.  People are hesitant to audition for shows that don't have a plethora or performance examples - or easy access to score/libretto.

Finding a Sherlock that meets all my and the show requirements is going to be difficult.

Again, thanks for all.
