It's likely that Russia will allow Turkish missiles. However, that would not be a significant technology transfer. Technically Russia could do this merely by passing on protocols to 'talk' with the S-400, and letting the Turks create their own missile. Even if some missile tech were to be transferred (I rather doubt it), the key part of S-400 is not the missiles - but the very sophisticated radar, control and EW systems. Either way, it doesn't get Turkey much ahead in designing their own missile defence system, and leaves them dependent on a potential (even likely) enemy.
