^^ This isn't a no chill method tho. This is a delayed boil.
I think you would prolly be alright. Not recommended of course, but likely ok. As you will be boiling everything the next day, there wont be any residual bacteria and anything that takes hold in the wort would be killed off in the boil. I would take as many steps as possible to reduce your risk.
Make sure the exposure to air is kept to a minimum.
If possible, dqr mentioned raising the temp to boil before going to bed. This is a good idea too as long as you can ensure no exposure to environment before the boil.
You could also try to bring the temperature as low as possible as quickly as possible. This would inhibit any unwanted growth in the wort. A deep freezer would be perfect for this.
Either way you do it, there is risk. Personally, I would wait for a proper brew day opportunity.
