Good idea.  For an trivial example,

--8<---------------cut here---------------start------------->8---
$ cat bibtex.tmpl
@example{ {{name}}@{{version}},
title      = {{name}},
url        = {{home-page}},
license    = {{license}},
abstract   = {{synopsis}},
swhid      = {swh:1:...},
repository = "WE HAVE THAT INFO",
author     = "?????",
date       = "?????",
}

$ guix show hello | recfmt -f bibtex.tmpl
@example{ hello@2.10,
title      = hello,
url        = 0.000000,
license    = GPL 3+,
abstract   = Hello, GNU world: An example GNU package  ,
swhid      = {swh:1:...},
repository = "WE HAVE THAT INFO",
author     = "?????",
date       = "?????",
}
--8<---------------cut here---------------end--------------->8---

However, 2 minor annoying comments:

 1. SWHID is not computed by "guix show".
 2. Typing the path to the template; aside recutils is not installed
by default, IIRC.

Well, #2 could be solved with something under ~/.config/guix/current/bin.

About #1, it requires some work and I am not convinced I would like
that Guix does it each time I call "guix show".

As much fields as possible.  As the example above more or less.  Well,
use bibtex-software as decribe here:
