I've been thinking of a similar solution for game states.  It would generally be clean and safe.  The only problem I've been studying is upgrading previous game states, because you don't want want to throw out previous ones.  I've been thinking of writing functions to upgrade one version of the game state to the next.  When you load a game state, you find its identity according to the "id" parameter, and upgrade it accordingly if necessary.

So you would keep the old structure, with the same id, and create for instance a new type game-state-2, with a different id, and a converter procedure update-game-state-1->2?

Cheers,
