There’s a problem with that, though. We might expect to make beryllium from lithium-9, through beta decay, (~50%yield), but lithium-9 is hard to obtain, since lithium-8 is unstable with half-life ~800ms. So you’ll need an intense, and highly focused neutron beam to double-bump lithium-7 nuclei, hoping they don’t fission in the process. the yield will be low (which explains why beryllium is rare, here on earth, anyway).
