It is very unlikely, the Chartists (despite the fears of the time and the sillier demands by the more extreme elements) were simply not a revolutionary movement.
At worst, you get another Peterloo Massacre.
You have to remember that the Chartist leaders had already been scared senseless by General Napier and his demonstration of artillery firepower, they knew that for the sake of their followers they had to avoid any confrontation with the military. In a strange way, you need to do away with a sensible general first so the Chartist leaders might feel more willing to confront the military but even then its hard to see a civil war developing.
