Definitely wouldn't be feasible unless Starship works out at scale. If it does, launch costs go under $50/kg. Here is NASA's SPS-ALPHA study, which estimates 15 cents/kWh with $500/kg launch cost and minimal technological development (pdf): https://www.nasa.gov/sites/default/files/atoms/files/niac_2011_phasei_mankins_spsalpha_tagged.pdf https://www.nasa.gov/sites/default/files/atoms/files/niac_20...
