Prepositions as image schematic and khoratic object a. Say what?

In light of my recent ruminations on objet a,* and recent email discussions with Balder on his upcoming paper,** I return to this post (p. 77) on Latour, prepositions, image schema and khora. In this post (p. 78 ) I ask how Latour integrates the modes and we got a vague reference to "variation itself....difference differences even more differently,” which I correlated with differance (aka khora depending on context). In this post (79) I said:

“Combine the above with what Latour said in this post about “variation itself” being that which contextualizes the plural modes and we might have something like the virtual differance at the core of an actant's autonomy.”

Then this post (80):

“Ah, I think we're getting to le differance with Latour's plasma, unformatted reality (80 and following). And on 83 we discern it by, like Bryant, drawing a distinction between the marked and unmarked space. And this circles around to my question about the more complex environment that a suobject translates through its marked space.”

In the following post I made a connection between Latour's serial description and Derrida's interation. At which point I started to make connection that differance and/or khora is the endo-relational structure of the universe at large. Here (80) I questioned per Bryant that differance is just on the 'inside' of an local object, since that object is 'inside' the non-local hyperobject universe-at-large's overpowering endo-structual gravity of differance. And here (80) I related it back to prepositions: “Differance is that which pre-positions identity and difference, i.e., the transcendental condition for their manifestation.”

And some thoughts from my emails with Balder. The preposition acts like khora in that it is that withdrawn core that prepares the space-time for actual occasions and is coterminous with them, a la Whitehead. Hence I'm wondering if prepositions, while parts of language, aren't themselves something prelinguistic and which tie language back to that basic categorical embodiment via image schemata? If I'm right about prepositions being more akin to objet a than being an actualization or local manifestation of a particular paradigm, then they might be more of an meta-paradigmatic function.

* According to this wiki entry, the 'a' refers to autre, French for 'other' "and Lacan's own exploitation of 'otherness.'"

** Balder voiced his idea for the paper during this discussion on p. 78.
