Denny,

I would suggest to use https://en.wiktionary.org/wiki/product as that strawman proposal.  Because it has 2 levels of Senses.
  3. Anything that is produced (contains 6 sub-senses)

To apply Daniel's thinking... I wonder...

his Lexeme Sense = Wordnet Sense ?
his Item -> Lexeme - Forms = Wordnet Synset ?
