It would be very nice if you could do this.

I tried out your patch and present.lisp (after removing the load of
cmucl-pprint-patch) using a cmucl built with your pretty-stream
annotations.  Despite some bugs in slime (possibly because I'm using
XEmacs and not Emacs), this looks really cool!  The unreadable objects
are clickable now, just like the regular output presentations.  And
since it's hooked into the pretty printer, I see that if I C-c C-k a
file, the slime repl buffer has the pathname of the file highlighted
and clickabe as well.  This didn't happen before.

This patch will be in the next snapshot of cmucl.  Thanks for the
patch!
