Hi steelwindmachine,
Outside of maybe using them for a guest bedroom or giving them away to someone who may like them more than you do … if you are feeling adventurous you could buy a new pillow casing (or open up the ones you have and reuse them or sew your own) and remove the material in your pillows and experiment with it in combination with other pillow stuffing materials to make a new pillow that you may like better. Some sources for DIY pillow materials are at the end of the DIY reference post here.
