There is no need to repeat the phases that do not change in your patch. If you have a look at icu4c.scm, there is an example using "alist-replace" for the configure phase that changes; moreover, it just patches a file first and then calls the normal configure of %standard-phases:

(alist-replace

'configure

(lambda* (#:key #:allow-other-keys #:rest args)

(let ((configure (assoc-ref %standard-phases 'configure)))

(substitute* "configure"

(("`/bin/sh")

(string-append "`" (which "bash"))))

(apply configure args)))

%standard-phases))
