Not that I have a clue re these "contortions" of have even heard of such... still, I would hate for the lack of knowledge to impede my offering an opinion or suggestion-

What happens when you open Font Book and then "validate" all fonts, and, "look for enabled duplicates"?

I'm thinking[?] that the Lucida Grande file itself, or the µS font cache is corrupt and may need (re)installation/purging.

Sorry if my help is not...
