I'm far from being a (neo)mutt power-user and I'm still learning, but
thought I'd share how I approached what I think is a similar problem.

I get emails from WebKit [1] with diffs which use pesky HTML and which I
still want to view as plain coloured diffs in my terminal (in neomutt).
So I set up a hook for these messages:

    message-hook '~s \\[webkit-changes' "\
        set allow_ansi; \
        set mailcap_path=~/.config/neomutt/mailcap-webkit \
        "

In that special mailcap I use a dedicated filter:

    text/html; ~/.config/neomutt/filters/webkit-changes 2>/dev/null; copiousoutput

which is based on filters I borrowed from aerc email client [2] (`html` and
`hldiff`):

    #!/bin/sh

    filter_path=~/.config/neomutt/filters

    $filter_path/html |
    sed -E -e 's/(\[|:)(INS|DEL)(:|\])//g' -e 's/^Diff/diff /' |
    awk -f $filter_path/hldiff

The key here is the `html` filter (check it in aerc [3]) which uses `w3m`
for rendering/filtering HTML in terminal.  This provides all links at
the bottom to follow (if I need to).  Also the aerc filter uses
`socksify` to avoid phoning home from HTML but I replaced it with a fake
proxy:  `http_proxy="127.0.0.1:1"`.

I'm not sure if any of this helps you, but maybe at least it inspires
some thought.

Cheers,
Kris
