SE have already staed why you can't log back inside your personal chambers or FC house, and it's because of how the game's client renders the house's interior not allowing it, so it's not going to happen I'm afraid.

As for for your other ideas, I agree with Judah, as nice as they are (and speaking as a casual RPer on Balmung myself) they're ultimately very minor additions that require a lot of resources to implement which are better spent elsewhere, so I doubt that it would ever be implemented.
