This is a good base for winter riding. Suspensions suffer from winter (salt, wet, oil viscosities etc.). and unless we talk deep snow, tire width should be fine. If you had started your thread as one "looking for winter bike", your bike would have been a good suggestion (besides a fatbike).
Studded tires also should be much cheaper in 2" than fat bike studded tires, or a new fat bike. Not sure if you have a second bicycle. But when you have weeks with clear roads, you may not want to use studs for long distances (though, nothing wrong with it). Really depends how your paths look like in real life every winter day.
