TBF 20,000g is totally doable. The spacecraft weigh 1 gram each, so that would be 20kg of thrust pressure. Assuming he spacecraft are nominally 2d in construction (a silicon wafer) and the pressure is evenly distributed, I see no reason why you couldn’t expect them to withstand 20k g acceleration. 20kg isn’t a lot to stack on essentially a chunk of solid glass if evenly applied.
