Storyline360: Swap base layer and other layer
Hello BenChia,
Thanks for following up with us. You will want to be sure that you are copying the object and then using Paste Special when pasting your layer content in a brand new slide, as my colleague Jose shared.
1. Right-click on the object and select Copy.
2. Go to the new slide and right-click on the slide and select Paste Special.
As this screenshot shows, you'll want to make sure Keep source duration and Keep source start time are checked. Depending on your setup, you may need to adjust the timeline of the base layer to match the timeline length of the slide layer.

Hello BenChia,
Thanks for reaching out!
There isn't a way to convert slide layers into base layers, but a quick workaround is to insert a blank new slide, copy the objects from a slide layer, and then paste (special) the objects into the newly created blank slide. 
Doing this will allow the objects you copy to retain their positions in the timeline. I’ll happily pass your requirement on to our product team, but you can also detail it more through a feature request here!
I'm sorry, but every object is pasted according to where the blue timeline cursor is marked, i.e. all at 00:00 (or wherever it is). The pasting does not let objects retain their positions in the timeline.

Thank you, Luciana! Especially for making a short vid clip.
Knowing about this 'Paste Special' feature is fantastic.
Not mentioned, but I tested, and it works for ALL (CTRL+A) objects copied at once.
The only thing to note as you cited above, is to adjust the timeline of the base layer to match the timeline length of the slide layer, or it does get cut off at the end if the 'new' base layer had a shorter total timeline.
I sometimes organize some content into secondary layers, as in the final stages of review, stakeholders may want to cut away base layer or secondary layer content, to make an e-learning module leaner.
