Anyone can learn to play right or left handed. You'll never see someone playing left handed in a major orchestra (yes, I"m sure there is an exception somewhere). Just play right handed.
There is more to it than just make a left handed instrument ...
There is a lot of people in an orchestra and so they all need to be on the same side otherwise the bows will hit each other and ... saddly ... it would look weird with what they have going on visually ...
