Exactly. We could generate a shot where there are two or three of them, then have a shot focusing on the guns charging, maybe firing, then cut to the shot of the Hosnian surface.

The only little gripe would be the intensity of the approaching laser of the Hosnian shot seems a lot larger than what the Dreadnought shoots, but if we cut it in a way were it seems all two/three dreadnoughts are firing together (either single rounds like in TLJ, or maybe a laser beam like the Death Star or the Battering Ram Canon instead) I think it would help justify that intensity.

And you wouldn’t necessarily need a shot of the laser impact the surface, because as the laser is approaching the camera and you hear the screams, you could hard cut back to Leia as she is reacting to the deaths.
