Is it even conceptually possible to build a LN register that's noncustodial, lightweight, and which can hold funds elsewhere (as shown in this video) even offline?

https://youtu.be/u5qtqycDFtk

key features:

• noncustodial, no intermediary

• receiving wallet can be offline (ie paper wallet)

• register does not have keys or access to funds but always can know the wallet balance

• no fullnode required

seems to me that this video really highlights the architectural differences between the BTC and BCH approaches. when you consider what's happening in this video, I don't think it's possible to replicate anything remotely as powerful within Lightning.

If I'm wrong in my assumptions I'd like to learn how. Note: I would have liked to ask this question in rbitcoin but I'm banned there.
