Since most up to date avatars are using full or partial BOM at this point, it's probably time for updates to how the system layers work. Adding the option to apply a BOM eye to left or right, and maybe at least a third aux channel for those who use extra eyes for fantasy avatars to have options to mix & match. When right clicking it in the inventory, it would offer the left/right/aux eye/all options to apply the eye texture to, which would basically keep the amount of texture load the same as if they were wearing a bunch of applier eyes and not require creators to go back and revise a backlog of eye releases.
