Nice, but take a care about vessel stability. A P-500/1000 is approx 4.8 T, while an Oniks is 3.0 T and a Kalibre can be up to 2.3 T depending on variant (quoting wiki). Assuming launcher tube mass is proportional to that of its missile (?) I don't think you will be able to pile 6x new missiles for each pair of old Bazalts/Vulcans without compromising her sea keeping.
With the talk about upgraded Oniks (faster, longer ranged) courtesy of new technology fuels, maybe a re-tooling of the Slavas to carry Oniks tubes would be a better upgrade path? Bazalt/Vulcan is an older aerodynamic design going all the way back to the old P-3 Shaddock (IOC in 1959) and its potential for upgrade must be just about exhausted by now? Modernised Oniks with a big performance boost might be a relatively low cost upgrade if the RuN intends to keep her 1164s in service for another decade or so?
Here's a question from left field... how do we know the modernised Marshall Ustinov is still carrying Vulcans? Have post-refit firing tests been observed? I would have thought it would be relatively straightforward to fit out the P-1000 tubes with liners to carry modernised Oniks. No evidence of course, pure conjecture, but such a conversion could be done with little more than mechanical installation of the liner canister, replacement of the firing console & electronics plus probably new cabling (not sure about systems integration of course, making new electronics function with the old). I'd trade Vulcans (no longer manufactured?) for enhanced Oniks any day of the week.
