Unitary Quantum Cloner: Micro-Macro Entanglement & CHSH Inequality

[StevieTNZ]

With a unitary quantum cloner, because it generates micro-macro entanglement, if we amplify one of the entangled photons using the cloner, does that mean that the corresponding macroscopic amplification is in a superposition (a superposition of V and H polarisation) until measurement? Would we see a violation of the CHSH inequality?

Also, if we measure the polarisation of the other photon, then send the partner photon into the unitary quantum cloner, would that produce the same result as a measure & prepare cloner (hence not produce a micro-macro entangled state), and thereby expect no violation of the CHSH inequality?

Perhaps another question - how fast can an unitary quantum cloner generate the macroscopic amplification? Is it in principle, any speed?
