Animating/Changing lights, textures in night-time baked scene to daylight.

I have a kitchen scene that is set during night time. Currently, all the lights are baked. I want to have a camera fly in during run-time that zooms into a specific part of the kitchen, and as it does this, switch the night time scene into daylight, activate real time lights and change all my baked textures back to the original textures. Also, there's a window with a textured plane of the outside sky... so that would have to be animated into daylight.

Am I gonna need specific scripts for all these lighting changes or is there a way to do this all within unity?
