Hmm, that sounds interesting. Let us know how it turns out.

COERCE-FLOAT-FUN (or coerce-float-fun; crazy CL case policy)
is defined in src/plot.lisp. It is certainly possible to create a
bigfloat version. It is probably easy to cover 90% of the
possibilities with some quick hackery, so I encourage you to
give it a try. We can sort out the remaining edge cases after
you make some progress on it.
