[plt-scheme] Renaming module identifiers

Is it possible to rename all exported identifiers of a module using a function
(symbol -> symbol)?

 From the documentation it seems only explicit renaming is allowed and must be
done for each identifier you wish to rename.  So then my question is, could I
add this functionality?

eg.
(require (rename-all some-module (lambda (x) x)))         ;; no change
(require (rename-all some-module (lambda (x) (gensym))))  ;; take an advil


Thanks,
David
