24" between rows ain't going to be much of a advantage except early on. I'd say depends if you yearly burn it off. Mine hasn't had to much of a hollow middle and I think it was because of burning. Didn't get it done this year and have a good size hollow area in the middle where dead leaves pile up. Thinking two rows would just do the same and just grow on the outsides of both rows without wider spacing. Think mine is around 10 years old and is 6' wide now.
I didn't quite follow what you were explaining. Probably my old age.
