Hi Robnclaire -
Welcome to My Swiss Alps.
I can see that you have been doing your homework. Unfortunately, there are very few hikes in Switzerland which qualify as "less travelled." The Swiss make it easy to get to trail heads, and the scenery is so spectacular that a lot of peole show up in the warmer months
There are certainly good hikes available from Kandersteg. (By the way, it is the Gemmi Pass, not Gemini). The Gemmi Pass is famous, and you will find a lot of hikers on it, and even more around the Oeschinensee.
The question of packing and unpacking is tough to answer. I hate to waste time checking in and out of hotels, and my compromise is 2-3 nights in one place; 4 if it is really a good location. (Such as Wengen) But, there are too many good things almost everywhere....sometimes when I am short on time and plan to visit several friends I end up with one night stands. However, I have been around Switzerland a lot, and I can pick and choose with some idea of what I am passing up elsewhere. ;-)
Near Luzern, you might like to hike some or all of the Swiss Path. (Auf deutsch - "Der Weg der Schweiz.")

Here is my take on an easy portion of it:
Here are some things to consider -
1.- A good source of information about the Jungfrau region might cause you to consider visiting there:
2.- The best link for information about hikes:
map.wanderland.ch/?lang=de&route=all&bgLa yer=pk&resolution=20&X =612240&Y=149000&layer s=Wanderland
Note the menu is in the link above. You can turn on transport connections, etc.
I turned off the menu to get more map in this one:
map.wanderland.ch/?lang=de&route=all&bgLa yer=pk&resolution=10&X =618020&Y=149170&layer s=Wanderland
If i enter the search term "Gemmi Pass" I get this:
map.wanderland.ch/?lang=de&route=all&bgLa yer=pk&resolution=1&X= 613289&Y=138338&layers =Wanderland
You can find out about some routes by clicking on them. Or, search by a town name, etc.
Once you have a major named route, you can get altitude profiles, accommodation information, etc. My only problem with this site is that I have to try a few different ways to search each time I use it...I have not mastered the tricks to quickly get to the substantial information available.
3.- SwissTopo is the most complete map for geographers, geologists, serious hikers.....
There are many "overlays" available.
Here, I have turned on hiking trails, and you get the color coding for difficulty:
map.geo.admin.ch/?topic=ech&lang=en&bgLa yer=ch.swisstopo.pixel karte-farbe&layers=ch.bav.ha ltestellen-oev,ch.swisstopo.swiss tlm3d-wanderwege&layers_visi bility=false,true&X=14 9711.06&Y=618032.66&zo om=5
Note at least one blue route shows - technical climbing.
4.- Suggested hikes in this forum:
Check under "Find Trails."
5.-You can certainly fit in a trip to Jungfraujoch.
To understand travel routes and times, use the SBB Timetable. The link in this forum is a good place to startm because it has some useful pointers:
The direct link is:
The new edition, now made friendly for tablets and smart phones, has just appeared. I am still learning my way around it, as I am am used to working from the older version that was best for desktops...lots of detail on one page. So, I can't give much guidance, but I strongly suggest that you spend time with it and a map. It will give you a good sense of the possible, and how long it will take.
Because you have mentioned a couple of famous and hardly "less travelled" destinations (Jungfrau and Birg) , I wonder if you might stay a couple of nights in that area, near the Jungfrau?

My favorite easy hike, which can be beautiful at any time of year and combines"easy" with stunning scenery, but, especially in September, is the walk from Männlichen to Kleine Scheidegg.
A few pictures are attached.
