it is the bringing the copper level up to the therapeutic level that is the dangerous part which is why I think seachem says do it over 48 hours..that is so you don't poison the fish with too much copper.
I totally agree that copper will kill fish..but as long as you keep it within the guidelines of seachem you should have little problems.
and adding cupramine will not effect the bacteria to where it will affect their ability to do their job..it is any live critters dying off within the live rock that may cause a small ammonia spike.

I'm not sure I understand what you mean? Are you suggesting that dropping a fish from copper free water in to water with 0.5ppm copper is any different physiologically for the fish then adding enough copper to bring the water they are already in to 0.5ppm in one go?
I'm pretty sure the reason the acclimation period is stressful for fish is because copper is a poison to them, and their kidneys and liver need time to adapt to the increased work they need to do to prevent the poison from killing them. You say you've had very little deaths with that method, which to me sounds like you have experienced fish mortality as a result of dropping fish directly in to full strength copper water. When the fish you're talking about can sometimes cost north of 200 bucks, I don't know if I would be willing to take that risk.
Also, it's not a good idea to have live rock, or any calcareous materials in a system where copper is being dosed. Copper reacts with it and falls out of solution.
