It would be extremely nice to be able to move some of the current Java
stuff into Lisp. To do that effectively, I think we need something
like ECL does: build an ecl_min in C (in our case abcl_min in Java)
which implements a rather small subset of Lisp. The rest of the system
can be based off the minimal lisp and implement the full CL spec.
However, this approach would need a good design. Without one, I think
we'll be lost.

That's probably - in the short term - the best thing to do, yea.
