On the question of bobbed hammer primer ignition: Would it possible to swap a m49 or 649 hammer in to the m36 to lower profile of the hammer spur hang up? Or even a hammerless type hammer?
I have bobbed several J and K frames and have had no trouble with primer ignition. Even with trigger jobs and lightened trigger pulls. I did a trigger job with lighter rebound spring for a friend recently and has had trouble with Russian steel cased ammo, but nothing else.
Regarding the hammer replacement, while I have not gone that route I don't see any problem with doing so.
There's one major downside to removing the hammer spur that doesn't get mentioned. Revolvers do malfunction. The immediate action drill for a slew of malfunctions that involve the trigger not being able to move is to reach up and cock the hammer. Once I reduce the "to do" list to manageable size, replacing the spur less hammers on my Js is going to happen.
Bobbed the hammer on the K-frame 65-3 heavy 3" barrel .357 magnum. A favorite 80's FBI carry option. Acquired an as-new example, found a new hammer replacement to bob; dremel cut-off wheel, grind sharp edge, polish, done. Filed off single-action notch so its double-action only.
