The company I used to work for is doing this to the engineering org in my current employer. It requires the leadership from the old company to be embedded in very senior positions, and it requires buy-in from the existing C-suite. There's a lot of backroom politics to change culture along with a bunch of work to prove yourselves to people who aren't involved in the backroom. There have been a bunch of points at which I didn't think it would continue but so far the original team has been pretty successful at rising.

Think of it as a reverse McDonnell-Douglas.
