No.  Wordlist rules operate on individual input words, not on pairs of
words.  (As an exception, there are some rules specific to "single
crack" mode that do operate on pairs of input words - e.g., on someone's
first and last names.)

Attached (as text/plain - this is important for some web-based archives)
are three trivial Perl scripts that can do roughly what you need -
combining two, three, or four input words, respectively.  You can
redirect the output of one of those scripts either into a "john --stdin"
or into a file (and use that as a wordlist with John).  Obviously, this
approach is only reasonable with tiny wordlists - e.g., with John's
default password.lst and/or with English/1-tiny/ wordlists from the
Openwall collection.
