[Conkeror] Lisp for conkeror?

[Evans Winner]

This might be stupid, but I was thinking, I believe it is
possible to write a simple scheme or lisp interpreter in
JavaScript[1].  Not knowing anything about JavaScript, and
being a refugee from the Emacs world I would love to be able
to write (at least simple) conkeror customizations in
something more familiar to me (i.e., more lispy).  Is this
realistic or reasonable or whatever?  Anyone already doing
this?
