I don't think the tropes could serve as gists on their own, but you can relate them to Dramatica elements by using them as the "nouns" in the gists. @jhull used to include collections of thousands of such gists (fantasy, sci-fi, western, thriller, etc.) as part of a Narrative First membership; I'm not sure if he maintains those any more but you could contact him. It's possible he plans on adding genre functions to the Subtext gist lists at some point?
An example would be take "confined spaces" and use it to make a gist for Subconscious: fear of confined spaces, or being claustrophobic.
Or take "monster" and use it to make a gist for Desire: lusting after the monster
The existing gists that end with "someone" or "a particular group" or "something" are particularly good for applying these things. You can end up with neat combinations you might not normally think of, like fearing virginity or lusting after insanity.
