I wouldn't do it that way. Effectively all the bacteria are in your filter, any bacteria that did come in with this substrate is insignificant. Taking it out in sections only adds to the work. If the tank isn't cycled it isn't cycled, what little bacteria may have come in on some substrate won't make the difference. Get the substrate right before you start stocking.
