There is no emacs lisp function to get the binary representation of a
cons cell, or a number or a string or anything, AFAIK.

So you won't be able to write in emacs lisp any function converting
values to binary any faster than prin1.

You may want to try it in C, adding primitive functions.  You will
still have to do a lot of work, like converting pointers into OID,

IIRC, there is a mean to save an emacs lisp image, so you could save
the whole data structure, along with the whole emacs in a new emacs
image, and then you'd run this image instead of a virgin emacs.
