Do you think this would be a good diet?

You need more moderation than that. I'm sure you would get sick of this routine after a couple days anyways. It sounds like you would hardly be getting 600 calories per day which is not healthy at all, you will slow your metabolism down a lot and you will not be able to lose weight. You should also add some bread or grains in there somewhere too. I'm not sure how much calcium are in all of those things but that's another thing you should look into before starting this diet, we need our calcium!
