While Arno is the master of knowledge here, I dare to reply because we did a similar or rather a more intense trip . We brought 8 days Swiss Travel Pass, which for me as an adult was around CHF 363 and for my daughter who is below 25 years CHF 309.
Our journey started and ended at Domodossola in Italy,and we did travel through Basel while staying at Wengen, Grindelwald and Lucerne.
If you could work out your timings, I am sure you can also visit Schilthorn during your stay at Wengen at hardly any extra cost. As the cable cars to Schilthorn are in stages, you can opt for some lovely treks enroute like Murren to Ginderwald etc.
Also from Lucerne,do have a look at possibility of visiting Mt Titlis, instead of both Rigi and Pilatus. Infact we had planned both Rigi and Titlis on same day including boat from Lucerne but due to circumstances had to cut it to Mt Titlis only.
so have a go at it.
