I am trying to imagine a series of 22,300 mile-long elevator stages. It could be done, but management of transfers would be a wonder.

Anyway, the stopper up to now was the main cable. If the solution to that is as good as in hand, then it is time to figure out the next hard problems.

I would expect that the stages would become exponentially longer as the relative change in gravity per mile decreased.
