Per FontForge's documentation, it can generate italic correction values, may be LuaTeX could make use of such feature and provide a way to generate italic correction values for fonts missing it, may be the tex height and depth too, if it isn't doing so already? Since FontForge has access to actual glyph shapes, it might be generating better guesses. I can generate sample fonts with FontForge for testing, if needed.
