I probably should have said "theoretically possible" rather than "technically possible".

These initial datastructures are created by running Lisp code.  So you'd want to be able to run Lisp code on the Macintosh (or whatever) that would somehow create data structures suitable for the iOS ARM.  That's just not the way most Lisps (including CCL) work.
