I just have one question for you. What technical research have you done on the algos used in x11? Did you miss the FACT that each and every one of them is designed to be ASIC friendly as that's one of the requirements to be SHA3 candidate? Or you're looking to "secure" LTC short term and hardfork each time ASIC manufacturers deem it profitable to build one?
You hit the nail.
By changing the algorithm on a regular base no ASIC company will invest in creating an ASIC for it.
