You can have multiple Virtual Tours per Tour:

But regarding multiple paths ... you can do it, but will require for you to have in the moderator, the correct path for the tour you want to open in the Virtual Tour Editor.
Beside that, you will have to Clone the tour to a new tour, and then build the Virtual Tour of that Clone.
