That depends on what kind of cameras they are.

Yes, unless someone has already written one.

There are standard ROS ways to publish stereo data.

The extra ROS wrapping for publishing camera data does not involve
much additional code, but does require a basic understanding of the
image pipeline. So, study the interfaces and look at examples of other
drivers, then ask more questions.
