I love this quote (from Interlisp-D: Overview and Status):
"Interlisp is a very large software system and large software systems are not easy to construct. Interlisp-D has on the order of 17,000 lines of Lisp code, 6,000 lines of Bcpl, and 4,000 lines of microcode."
That said… we need the “lisp machine” of the future more than we need a recreation.
There is Mezzano [1] as well as the Interlisp project described in the linked paper and another project resurrecting the LMI software.

So large. :)
