Nice. i've frequently used my A 400/5.6 with the A2XS converter and the
Kirk flash extender. Pretty close to the same thing. It yields good
results. Most of my dragonflies were shot with that setup. Like this
one:

What was the shutter speed? The flash makes all to difference in the
world - allowing a high enough shutter to freeze the subject.
While being doable I don't think I'd want to live with the focus issue
@ f11 for many shots.

Subject: More about birds on a budget
Thinking about the latest thread on what lens for bird photography
without breaking the bank, I went out and did a quick field test.
Here is a 300/4 with 1.4x extender AND 2x extender for a total of
840mm f11 equivalent. I used a Sigma flash with Kirk flash x-tender
for a bit of extra light. The bird was about 50 feet away and this
is quite a crop and resized for the web, etc, etc. (It's crappy
composition; I hate the looking-up-perspective, but it's a pretty
bird: a Northern "yellow-shafted" flicker (Colaptes auratus) a type
of woodpecker common around here).

As a test I'm happy with the sharpness, color and lack of any obvious
lens artifacts. The combination of lens and 2 TCs was a bit
difficult to focus due to so much loss of light, but definitely
doable.
