Long time duvet user here, switched from regular blankets.
You can certainly try looking for a duvet cover that will fit, but you‘ll specifically have to measure your current covering and see if the cover you like will fit.
Duvet covers don‘t mean you don‘t have to wash the thicker blanket. It just means you need to do so way less often. Our usual cycle is washing the cover and then the duvet has to be thrown in the dryer every 2x the cover gets washed or changed. This helps knock body dander or pet fur out, and of course kill the mites or bacteria that live on all of us, and this all helps keep odors away. About every 3rd or 4th change, the duvet gets washed too.
So in other words, you should still wash the big fluffy comforter. But, if you can find a duvet cover for it, you can wash it less.
