Not yet done perfectly well, but basically it is working now, using Lua
plugin. It requires two small scripts, first one in hook/compose_created
to install an additional item into popup menu:

--- 8< ----------------------------------------------------------------

local compose_window = ...
local xmenu = '<ui>' ..
               '<menubar name="Popup">' ..
                '<menu name="Compose" action="Compose">' ..
                 '<separator name="Separator2" action="Compose/---"/>' ..
                 '<menuitem name="Test" action="Tools/LuaScripts/OpenWith..."/>' ..
                '</menu>' ..
               '</menubar>' ..
              '</ui>'
local mid = compose_window.ui_manager:add_ui(xmenu)

--- 8< ----------------------------------------------------------------

and second one to be executed in compose/OpenWith... (file name is used
as menu item label, thus the name):

--- 8< ----------------------------------------------------------------

local compose = ...
local attachments = compose.attachments
[[ extract necessary file name from table get above just get into fname ]]
os.execute("xpdf " .. fname)

--- 8< ----------------------------------------------------------------

Exact binding for compose.attachments is not yet done, but I am able to
get both attachment table and selected items list for compose window,
just those pieces needs to be put somehow together (or I'd like to do
it this way).

So if you'd like to test it, I can send you necessary sources to build
Lua plugin (it is not yet in official repository, but it is easy to use
if you are able to build from source).
