Interesting long crossing (Überschreitung) via several peaks. The first one - Seebergkopf - is not a particularly spectacular one. Soinsee should be totally worth a visit though and Rotwand is one of the most popular hiking destinations close to Munich. The path from there to Taubenstein peak is not problematic, the peak itself includes a bit of scrambling. Going down from there can be done in the summer also with the Taubensteinbahn (operating only in summer).
The route can be varied and Seebergkopf - the first peak - omitted, thus reducing the altitude gainby couple of hundred meters.
The part between Seebergkopf and Rotwand I have never done myself, so the tour planning there is completely relying on the map!
