Earthdigr-- Am very familiar with your wonderful hiking opportunities in OR-- I live in the northern Sierras. Altitude per se should not be a problem for you, but elevation change is definitely something to be aware of. Hohturli is just shy of 8800 feet, and Bunderchrinde is maybe 800 feet lower than that. The Kandersteg valley is at roughly 3500 feet, so you can see the task at hand. If you take the lift up to the O'see going to Hohturli, you shave off maybe 1400 feet vertical, which still leaves some 3800 feet of climbing for the day. It's a stunning walk, however, and the nice thing about an out and back route is that you can turn around anytime. Bunderchrinde, since it lacks any lift assist, is perhaps the more ambitious outing, with about 4000 feet of climbing from K'steg.
I'd recommend against trying either Bunderchrinde or Hohturli in bad weather. Both hikes are steep, with some exposure in places, and the predominant rock is shale, which is extremely slippery in the wet.
BTW, since you are also spending time around Wengen, I'd suggest buying a copy of "Walking in the Bernese Oberland" by Kev Reynolds. It covers over 100 hiking routes for the area from West of Kandersteg to Grindelwald, including the hikes I've described.
