I think that's a great idea - I've been a huge fan of this film and the commentary is by all accounts fascinating. I was in the audience when Cronenberg was interviewed by JG Ballard when the film came out as part of the London Film Festival before all the hoopla of "Ban This Car Crash Sex Movie" (a real UK front page banner headline in a "news"paper !).
If you've seen the preservation of The Game or Se7en that digitalfreaknyc has released - I'd say something along those lines would go down a treat - especially if you just capture it as a commentary only-track. It's far more effective that way.
