A couple notes. Running your numbers through Ai it looks like it would weigh about one ton per km of wire. And possibly much less if you’re ok with more power loss and high wire heating. Since this is a short term use that might be fine.
But on top of that the extreme amount of power is only needed because we’re trying to get up to speed as fast as possible to minimize gravity loss.
If we’re not carrying our fuel for the first stage it’s conceivable we only need enough power to hover the unit and gradually get it up to top speed.
I know it’s still a far out idea but might be workable from first principles.
