If these type of organisms live only in specific size sand sediment, I can't see them existing at all in live rock, no matter the quality.
Even though live rock can appear to make a dsb "live", I think that there is room for improvement with regards to diversity.

That is why when a reefer wants to seed his tank it is a good idea to borrow some sand from an existing system.
