I have a general question about all the cooling hoses on the
diesels. Has anyone ever welded or brazed all (or some) the angles
and "T"s out of steel/copper/stainless, leaving mostly straight
hose sections that could be sourced almost anywhere?

I have done that on various vehicles for coolant and turbocharger  outlet
plumbing.  I have a "rotary draw" tubing bender with mandrels for many sizes
of tubing.  I made up sections of tube with bends.  You could also miter
angle joints, but they would need to be TIG welded with care so as to avoid
leaks, MIG does not work good enough.  Maybe gas welding would work.
I have used stainless when I had it around, but have also used mild steel
"ERW" tube and found it to last several years without any signs of
corrosion.
