My city uses 2011 NEC.
I would like to install a 125 Amp rated Spa Panel as a subpanel directly below my 200 Amp main circuit breaker panel to be able to use two 50 Amp GFI circuits. I already have this Spa Panel with a breaker and would like to use it:

My main circuit breaker panel is flush mounted in a drywalled 2×4 wall. The spa panel has an open knockout in the top that would align perfectly with a knockout in the bottom of my main panel. I would use a piece of straight conduit to connect the two panels.
My question is:
Can the spa panel be recessed/flush-mounted in the wall or is it required that it be surfaced mounted to the wall?
The reason I want it to be recessed/flush-mounted is so I can use a simple straight piece of conduit to connect the two panels. Surface mounting would require using flex conduit that would poke through the drywall. Also, the spa panel is hanging off the wall in a high traffic area vs. a clean out-of-the-way flush mount.
This is a picture of what I currently have that I'm not happy with. The conduit body at the bottom goes into the front of a junction box (does NEC allow that?) and the junction box has a piece of straight conduit up to the bottom of the main panel in the wall you can't see.
If surface mounting is required, I'll do something like this with flex conduit.

You are treating a "spa panel" as something special when it really isn't. Considering this is indoors, you can get away with a standard indoor breaker enclosure (NEMA 1) instead of the weatherproof (NEMA 3R) "spa panel" box. In addition, the spa panel looks to be designed solely for surface (not flush) mounting -- flush mounting may cause issues with the door, for instance.
I would get a standard 125A main lug indoor panel (your existing spa panel uses GE THQLs, so get a GE panel if you wish to reuse the breakers from the spa box) and configure it as a subpanel instead -- while your current setup complies with Code insofar as you're able to get access to the junction box with the conduit body hanging off the front, I agree that it is a rather ugly kludge.
