Quick answer is Yes, but what exactly are you doing? Have you set it up already? If not, are you saying the base rock you are going to put in is dry, so you want to kickstart it with ls? What?
Also I would add a couple chunks of older Coralline covered Live Rock to the mix....... It will turn the base rock into Live Rock quicker and will be of more benefit that way.
This may sound strange but you need coraline to get coraline so as stated add a piece of rock with some nice growth and use a tooth brush to release the spores from the exiting piece into your water stream
