I offer one tweak: what is the value of the CTO in your scenario? Probably nothing. Why is it necessary for engineers to work in a central engineering function? Why not closer to the problem (in this case marketing) where they can be the stars and not just a "shared resource"? The problem with the shared resource model is then that Marketing can just decide to hire outsourced engineers as contractors and then the know-how is not kept in the company.
