Please help if there is any tool that does this.
Yep. Its called an 'Editor'.
If you get a really random one...you will get the random effect you want.
Look up mulitcam editing in the PPro docs.
Basically: First, create a "source" sequence. Each video feed on it's own layer in the timeline. Sync them as required.
Next, create a new "multicam" sequence. Nest your source sequence into the multicam sequence by dragging the source sequence icon from the Project panel into the multicam timeline. Enable multicam editing on this sequence. Notice that this nested squence shows you exactly one video feed. This is normal, not to worry, all will be clear soon.
Now, open the multicam editing monitor. You'll see all of your different camera angles on the left hand side, and the "current" angle on the right hand side -- this corresponds to the camera angle on the left hand side with the highlight around it. Use your pointing device to select which angle is active. Start your video playing. As it plays, use your pointing device to pick which angle to show at any particular time by clicking on a camera angle on the left hand side of the multicam monitor. Be quick, this is real-time work. When you stop, you'll see the cuts made on your timeline. Each cut is identified by camera number, which corresponds to the video track number of your source sequence.
Finally, go back through your timeline to each cut, and use the rolling edit tool to move that cut back and forth to fine tune the location of each camera angle change. You can do this as often as you need to.
It sounds complicated, but in practice it's simple and quick.
