I don't think a deal built around Provorov for Miller is realistic at all. VAN is looking for RD in particular and unless they're able to move OEL somehow (who has previously said he doesn't want to move again), there isn't space in their salary cap for another Dman making what Provorov makes.
It's more likely they would do something like Miller for 5th overall + JVR.
As for PHI, the only way I see a trade scenario with us if it's essentially a 3 way deal and it's Provorov going to Team X (ANA or LA) and then it's JC going to PHI, perhaps including #5 or perhaps not. It could instead be a package built largely around assets obtained in the Provorov trade ++
For example, here are 2 scenarios:
1) Provorov to ANA for #22, Calle Clang, Max Comtois. Then, Chychrun to PHI for pick #5, Calle Clang, PHI 2023 3rd rounder, JVR ($2M retained).
2) Provorov to LAK for #19, Grans, 2nd rounder 2023. Then, Chychrun to PHI for pick #5, Grans, LAK 2023 2nd, PHI 2023 3rd rounder, JVR (no retention).
