If you're based at Basel, some of the trips you've suggested could be long days especially if travelling with children.
On one of my trips to Switzerland, my children were eight and five. Most times they enjoyed the travel but sometimes they weren't overly interested (possibly because they were a little tired) even when we were passing through magnificent scenery.
There are plenty of options a little closer to Basel. But I would suggest you consider a mix of "shorter" and "longer" days.
There will be plenty of people on here who can share knowledge and offer suggestions but it's a good idea to check the resources first so you have a better idea and understanding of what you really want to do.
PPPPP - prior planning prevents poor performance ... but no matter what:
enjoy your travels!
