anonymitiy by offshore Foundation/Trust

Hello

I am new a read some things about anonymity here. I am looking for a legal structure of anonymity and thinking about an offshore Foundation/trust e.g. in Nevis.
I need a company for legal business in switzerland. So I think to have a Nevis Foudation. This is owner of a US-LLC as Holding (no register of owners) and the LLC is owner of the CH-company.
If someone is looking in the CH-register, only owner of the US-LLC is known. In US you dont know where is owner of the US-LLC. But if you can find out there you only see a Nevis company is owner of the US LLC. Because the Nevis register is not public you cannot find out who is the real owner of the structure. And if you set up a Foundation......nobody is owner of it ;)

To the professionals: Do you think this works?

This is only to save my assets, espcially the CH company. Taxes are not the main thing. And not for illegal business needed ;)

Any suggestions are welcome.

Thanks
