> the 24-70 is a great piece of glass but makes me lazy
Well, it doesn't make you lazy. Perhaps it allows you to be lazy, but it sure isn't forcing you to zoom at gunpoint...
Taking you at your own word, I seriously doubt you'd actually use an 85 if you had it. It would be simpler to take a step toward the subject and keep the 24-70 on the camera. If there's anything to be done, arguably the answer would be discard the 24-70 and replace it with a 24-120/f4 - or even a 28-300.
