I also remember reading that such a system can exist, but can’t find a reference. It’s probably not that surprising, though, given that the proposed system has one large star and five minor ones, making it similar to a system with one star and five giant planets. Putting a planet in in such a way that it only has a night every 2000 years may be the only tricky part (giving it a much smaller orbit than the minor stars would help avoiding nights, but giving it a single moon that can cause nights once every 2000 years?)
