Interesting idea, looks like you got it figured out. I would however urge you to use double pole double throw relays instead of single pole double throw so that you are switching both leads. That way there is no current present in the lamps that are off.

To repeat the sequence the timers just need to be programed to have two on cycles each. Timer 1 would be on for the first 6 hours, off six hours, on six hours, off six hours. For example: on from 12 am to 6 am, off 6am to 12 pm, on 12 pm to 6 pm, off 6 pm to 12 am.

Timer 2 would be on the first 3 hours, off 9 hours, on 3 hours, off 9 hours.For example: on 12 am to 3 am, off 3 am to 12 pm, on 12 pm to 3 pm , off 3 pm to 12 am.

Timer 3 would be off the first 6 hours, on 3 hours, off 9 hours, on 3 hours. off 3 hours. For example: on 6 am to 9 am, off 9 am to 6 pm, on 6 pm to 9 pm, off 9 pm to 6 am.
