They wont be considered for adding back unless technically possible for the EJ Kai. Which based on the report we currently believe to not be. There was no upgrade kit for the EJ Kai in this area.
It's not the same case as Hellfires on a Lynx as that was actually tested and offered, the same with all other examples like the MiG-21SPS which has upgraded and modifications done to export PFMs which is what the SPS is.
