Why not someone with an aviation safety background? I work with people who do that for a living. One was formerly a systems engineer, the other has been safety for most of his career. If you can find a Designated Engineering Representative with the right mindset to be an executive, that would probably check all of your boxes.
I don't think the selection needs to be quite that narrow, but the CEO and a majority of the CEO's deputies should come from backgrounds of designing or building aircraft rather than finance. Let a finance weenie be CFO, and a computer weenie be CISO, but people who really know Boeing's core businesses should outnumber money types.
