Hi all!
Was finally able to hack something that
works! See below:

Yes it's possible. The trick is to use
"this-package" which can *only* be used inside a
package definition and no where else. Stumbled
across that when poring through some guix package
definitions, moreso skriblio.
Here's my working phase:
--8<---------------cut here---------------start------------->8---
(add-after 'install 'generate-dependency-file
(lambda* (#:key inputs outputs #:allow-other-keys)
(call-with-output-file
(string-append
(assoc-ref outputs "out")
"/lib/python3.8/site-packages"
"/wqflask/DEPENDENCIES.md")
(lambda (port)
(format
port "
#### System Inputs (generated from Guix)
|Name | Version | Home Page | Description |
|-----|---------|-----------|-------------|
|~a|
"
,(apply
string-append
(map
(lambda (input)
(let* ((pkg (cadr input))
(name (package-name pkg))
(version (package-version pkg))
(home-page (package-home-page pkg))
(description (package-description pkg)))
(string-append
"| **" name "** | "
version " | "
home-page " | "
description " | "
" |\n")))
(package-propagated-inputs this-package)))))
)))
