Yes, a broken belt will be a real problem and is very dangerous. Rotating the tires will help to identify which tire is the culprit. If you see a sidewall bulge you may have a broken carcasse cord - in which case you need to replace the tire before it firestones.
Also there is the general design of the tire or slight build variation that can cause radial force variation even with all of the belts intact. Every tire has radial variation harmonics that will show up at certain speeds. Picture it as a bicycle rim where the spokes are all springs - a weaker or stronger spring anywhere will show up at speed. The more variation, the lower speed it will show up at. As speed increases, the weaker and stronger springs combine forces and you get even more vibration - i.e. you may get a thump every 5th rotaion and another thump every 21st rotation. Poorly designed or constructed tires will show the vibration at highway speeds. A well designed tire shouldn't show this until you are well above the speed rating. Since you have access to another set of tires I'd suggest you try them out before you spend a bunch of money replacing suspension components.
