A defvar can trivially be moved from Lisp to C.  I don't see any
obstacle here.  As for functions, it's even easier since you can rename
one of the two from `foo' to `foo-internal' or somesuch and move some
code from one to the other.  We've already done such things for lote and
lots of functions.  There's no technical problem here.
