Don't think it would make the coin completely ASIC resistant. Remember dark-coin with its X11 algo? In 2014 everybody assumed that an ASIC could never be designed for X11 because it has 11 different algo combined into one.

If they wrote 24 different algos and changed them every 10 days, then they would just design a similiar ASIC which can switch algos when the switch happens. Most likely they won't do it due to the small miner reward but if it was a coin like ETH or BCH that switched to this algo then you would see there would be ASICs being designed for this.
