800s? I'm assuming you mean 600s? If so, then no, you're not gonna get much more than 3' of vertical coverage from each 600, so stacking the plants would be pretty useless unless you were also going to stack the lights.
FWIW, my current setup uses 4 600s in an 8' vertical section (although I'm obviously not growing trees currently).
