Hello sueoz, and welcome to the MySwissAlps forum!
It's not possible to combine pass discounts. You'll have to buy Jungfraujoch and Schilthorn tickets using only one of your rail passes. If you use the Swiss Half Fare Card, you will get a 50% discount on the entire trip. With the Regional-Pass Bernese Oberland, you'd travel for free as far as Kleine Scheidegg and Mürren, and get a 50% discount on the remaining legs, so that would be the best pass to use. By the way, it's worth to calculate carefully whether you need two different rail passes. In many cases that's not the most economical solution, but it all depends on the specifics of your itinerary. Here's how to find out which (pass)es are the best choice for your itinerary.
In order to find out prices with pass discounts, you'll first have to find regular non-discounted fares. You can do so by entering your trip in the timetable (enter Gstaad or Zweisimmen as your via station to make sure the timetable provides Golden Pass connections) and by clicking 'Fare/buy'. Next, download the validity map of the passes you're interested in and check which discount they provide for this route (I've already provided the links to both validity overviews above). For example, you'll find that the Swiss Half Fare Card grants a 50% discount on the entire route. Does this help you out?
