There's lots to do for a hiker with a bit of experience. You could walk up to Gleckstein hut which is on the flank of the Wetterhorn. The walk is quite exposed in places and you have to walk through a small waterfall, but the hut is a popular excursion for day trippers and overnighters. If you plan to go on your own, phone ahead so the hut warden is expecting you, and tell someone where you are going before you leave and phone them when you arrive to let them know you've ok.
Something I've always wanted to do that you may like, is to walk down the Aletsch glacier. This is a 2 day guided walk starting at the Jungfraujoch, with an overnight stay at the Koncordia hut. This isn't a solo hike but i think it would be a fantastic adventure. I just have to convince my wife.
