Thank you for your patience and interest in Intel RealSense technology. Below are the answers to your questions.
1. The order of camera enumeration is not customizable and the camera IDs are not modifiable.
2. The RealSense SDK does not provide a native method for point cloud registration. For further information you may want to see these articles: https://software.intel.com/en-us/articles/intel-realsense-technology-and-the-point-cloud and https://github.com/IDLER1229/Registration.
3. The SDK does not natively provide a method for doing this but it can be done programmatically. See this article: https://software.intel.com/en-us/articles/perpetual-computing-generating-3d-from-depth-data.
I hope this information is helpful.

I am also working to implement a 3d scanner using multiple cameras. I wonder if this can be done using the RealSense SDK. I looked at the example 3d scanning code, and it looks like mayb it is possible to modify it to aquire images from multiple cameras and then reconstruct all the images together.. But would it work? Or is there aother way of doing this?
The RealSense SDK for Windows does not allow for multi-camera capture but the RealSense Cross-Platform API (also known as librealsense) does have this capability. You can download it and get more information from: https://github.com/IntelRealSense/librealsense.
Librealsense does not provide scanning MW so you will have to develop that layer yourself.
There are other issues you will have to solve that are much more difficult. First, having multiple SR300 cameras pointed at the same object causes very bad destructive IR interference in depth. Many people have tried to get this to work by turning the lasers on and off then trying to synchronize the frames. Very awkward. This use case is not supported.
The R200 camera may be better suited but at close ranges we have also noticed some destructive interference when two cameras are pointed to the object simultaneously. You will have to test this in your environment.
