The only problem is how are you going to get us to play and rate your game? I want the jam to be open to a wide audience however, in your particular case, I'm unsure of the logistics. Tell us more...
I think that's a good idea. All the traditional games are going digital. If not you can still post your game and see if the community will be able to give you feed back. But you need to have a page for the game for them to provide feedback to you, if they decide to setup and play your table top game.
