As much as I'd also like the storms on nauvis, I think it's a binary option for surfaces so for it to work you'd need either lots of ruins spawns to build your early base under or some earlier tech version of the rods. But then the issue is that it would be too easy to power everything as long as you have enough accumulators... If somehow attaching the lightning storms to a specific biome becomes possible then that would be the best option so fingers crossed!
