I would hang fire for the cement as if it turns out to be a small scale event, you need to buy a new bog or will be stuck burying your poop while everyone else is flushing again

Yes, a short term event would prove a bit expensive with this technique. But as you said at the start the problem would arise not when pumping of sewerage stops, but when the material starts to ferment in the sewers. I guess this would take a little while to happen, depending on ambient temperatures, so it will be possible to wait a while before sealing off the bog once and for all.
