Well, CRS, are the small matters of cable fill, bending radius, and -arguably- suitability for use.
Oddly enough, in such situations I have almost always been able to replace the conduit body with a proper box - with surprisingly little effort. If the job is a real nightmare, just use two boxes and another splice.
As far as that light pole goes, I have drilled and tapped 1/2NPT threads in several similar situations. I was not aware of the braze/weld requirement. I must stress, though, that you either need that metal to be really thick, or put lock nuts on both sides of the hole. I don't like doing this, simply because the pipe is generally then subject to damage.
I could go on for pages as to how I think poles should be wired ... and I have many pictures of various attempts to bring power to poles. I can't think of a better situation to illustrate the difference between 'good trade practice' and 'code minimum.' All I'll say at this point is that 'code minimum' installations are generally unable to be maintained or repaired.
