While it is of course possible, whether it is feasible or efficient is a different matter. If you do not have some kind of follow, eventually the other characters will wander off of the path your main is taking, meaning you will have to stop and gather them up again. It is also much harder to turn everyone exactly the same with a mouse. ISBoxer in WoW is about as close as synchronized mouse-movement gets but even then it is subject to the quirks of computer systems in general.
