Nice, thank you! I am now torn between your suggestion and air-layering...I have similar size ficus benjamina, and needed both root prune and chop, so first i had a look at the roots, they were potato size, took me 2 repots to get ride of them.
After i could see growth again, i let it grow and mid summer i chopped, half what initial desire was, also hard prune branches but leaving some foliage on them. it survived everything so far and its growing well, this year i will chop it further down to desire size - btw you will get a lot of new growth on lower parts after first chop, so design might slightly changethat happens to me and i do not regret it.
on top of that, they root very easily even thick branches, you can have few more trees
so now im a spring no. 3 of entire operation
Good Luck.
I would repot and chop it first at the red line -

Very tempting! If I wanted to keep everything above the magenta line, do you think I could air-layer there?I think I would air layer my way down a few times to the lowest desired portion. That's got to be faster.
I would definitely need some more pots for that... If only there was a place I could get some beautifully handcrafted potsI'd get anything above this clump first, then this clump. Then this 2 segments joint.

The base is almost useless I'd imagine. Though thread grafting a "new leader" through every few inches may get you a few more stout trees from down there over time.
There is better growth habits exhibited by benjamin, so grafting other foilage could also be considered.
