S,
the structures you have listed have been done in paper, but not at 1/33. the dragon's teeth look very nice. if you google "atlantic (or atlantik) wall" you will find the information you seek, including a schematic of one of the typical, smaller "regelbauen". i'm currently doing a tobruk and anti-tank wall for the MMiP #27 at paperworlds in 1/72. good luck. cheers, c.b.
