Depending on the weather, the trails around Wengen will open/close as the operator assesses the safety (note: the Swiss are risk-managers, not risk-avoiders so conditions don't have to be perfect). The Männlichen-Kleine Scheidegg trail does, though, get slippery ice oozing over the track. It can take a few sunny days after snow before the track is open. You can check the tourism channel on the TV or the big board at Wengen railway station to see if it's open.
It's a stunning walk (not really a hike) - the Eiger feels close enough to touch. So I hope you get to experience it.
However, if the track is closed, perhaps you could consider going by train to see similar views. Wengen to Kleine Scheidegg (KS), then KS to Grindelwald. You could stop and wander around KS - even up the track behind the teepee, which takes you to the start of the Männlichen track. Also, behind the hotel are good views, and it's fun to sit on the terrace at the station and eat rösti and/or spätzli with the huge alps looming over you.
After you've exhausted the possibilities at KS, catch the train down to Grindelwald and you'll travel through the scenery you would've seen from the Männlichen hike.
Then you could do the trip in reverse and spend your afternoon going to Lauterbrunnen and on to Luzern.
If the weather's fine and you haven't yet been to Schilthorn or Mürren they are also nice possibilities if the Männlichen track is closed. They're just up the hill from Lauterbrunnen and easily do-able in your time-frame.
Have a nice trip!
