You can't retrieve a part of an object, so the answer is no.

Perhaps a better bet would be 

    export @Name @Address
    def @Recepient
        named @Name {}
        named @Address {}
        # ...

Use crossreferences, e.g. @Recipient&&preceding @Open address@hidden to
retrieve recepient name from an invocation of @Recepient in the body
of the letter.  Note, that this won't work for the first page header
since there's no @Recepient that precedes it.

Original one.  The example you refer to demonstrates this (@Bar from
@Base still uses @Foo from @Base despite redefined @Foo in @Derived).

Take a look at Jeff's letter style.  Put name/address into paramters.
Invoke a symbol that you will xref to before @Document so that it
precedes all pages.  Wrap @Open (see above) in a convenince symbol.
Use this symbol in your letter setup file in headers/footers.
