So...Conway's Law :)

There is also the "reverse-Conway maneuver": Structure the org to produce the results you want.

There are other ways to tell people how to behave than shifting their reporting lines, but some leaders haven't heard of them.
I actually like the strategy outlined in the OP (Absorb and Split). When this has happened, it's always lead to a much better outcome than when you start splitting and creating teams prematurely.
You can stand up a sane thing that you enjoy interacting with and then maneuver to have the org and systems match that new structure.
