It would never work. Impossible with English - there are too many things which don't have words whose first meanings would describe them, so they have to rely on second-third-fourth-nth plus context. You have already used a couple of words in their second (or further) meanings:

"you make my point" - Terry is not the manufacturer of your conical tip

"international" - now used predominantly to mean "foreign" (as in "we ship to international addresses", or "international languages"), while you used it in its obsolete meaning
