Almost everything you mention is available in current models, or as custom mods. What I would really like to see is:
1. Larger glove box.
2. Functional map pockets on the doors.
3. Move the rear view mirror closer to the top of the windshield.
4. An available storage unit with the overhead map lights.
5. Keypad built into the door like the sedans have.
5. Can be purchased. I posted about my experience with locking my keys in my car and someone posted the link.
