Scrog tips/ideas on harvesting half

I've got a 4x4 scrog going with 6 plants, three are indica hybrids other three are sativa. I need some ideas on how to take the 3 out (whole) while keeping the other side of the net up to let the others finish.
I was thinking of running a cord/bungee down the middle, tying off the side staying and hoping it holds. Then cut the other side out and remove plants. Anyone have tips/experience? Trying to avoid a Jenga situation.

I think you learned why multiple plants in a scrog is a bad idea

Multiple strains yes. First round worked out, but this one's giving me probs.
