A mini roundabout often doesn't usually have a diameter. Most are jus normal junctions which have been made mini-roundabouts to set a priority.
So in terms of large vehicles it is the same problem as any other junctions, whether they can turn left or right. In the UK, U turns are prohibited at mini-roundabouts, which I would have thought would be the main usecase for a diameter.
