One of the things that makes the minion method work is that there simply isn't airflow to all the charcoal all the time. Some of it has to burn off for other charcoal to light. I think the big problem with wood chunks will be eliminating enough air space.
If you packed them tightly in a charcoal basket, it's certainly worth trying.
Usually when people want a nap with their stick burners, they burn a load of charcoal in a basket in the fire box. That buys you several hours of sleep time.
