The manual mentions the ‘package-input-rewriting’ procedure in section
“8.3 Defining Package Variants”.  I guess you could write something like
this in a manifest file:

--8<---------------cut here---------------start------------->8---
(define custom-package
  (package
    (inherit some-package)
    ...))
    
(define package-custom-cflags
  ;; This is a procedure to replace SOME-PACKAGE by CUSTOM-PACKAGE
  ;; recursively.
  (package-input-rewriting `((,some-package . ,custom-package))))

(packages->manifest
  (map package-custom-cflags (list package1 package2 ...)))
--8<---------------cut here---------------end--------------->8---

Totally untested though.
