Why can't you use regular encapsulation?

I think it would be better for you to see if you can do this is 
as a rewrite instead as that doesn't affect the type system.

E.g. C# introduced "record" in addition to "struct" and "class" 
to get slightly different value semantics, but as far as I can 
tell it is only a rewrite.
