NSM and Glossotechnia

An idea has occurred to me for a possible variation or refinement of
Glossotechnia.
In addition to the main deck and the translation challenge deck, I
might add a deck
containing the 60-odd words of the Natural Semantic Metalanguage.  Each turn
a player would coin one word on their own initiative, using charades,
drawings, etc
to define it, and then would draw the top card from the NSM deck and coin a word
for that concept as well.

I'm not sure if I would want to include the entire NSM vocabulary, or
just a subset
of those words that are harder than average to define with charades
and pictures.
Or I might add those cards to the main deck; when you get one of those cards
in your hand, you can play it to coin a word for that concept without having to
go through charades etc.

With a separate NSM deck from which a word is drawn every turn, the
vocabulary of
the language would grow about twice as fast, and players might sooner be able
to start using words of the game-language to define their new words.
