The answer to what you ask is: yes, lisp requires few bytecodes

But there is more than bytecodes: you would have to rewrite the
library C around it providing objects and functions to manipulate
them.

The other thing is that you will need is the equivalent of
setjmp/longjmp to implement nonlocal jumps such as GOTOs, RETURNs,
etc.
