A little more information about what you mean by "fake" rosbag would help people point you in the right direction. Do you want to copy a subset of topics? Modify data on a topic? What modifications should the "fake" rosbag have?

Regardless of what you want to do, there are rosbag APIs in both Python and C++ that allow you to read, modify, and write to rosbags. Given a little effort, you should be able to arbitrarily modify the data in the original bag file to create the "fake" bag file.
