That wouldn't give enough time to swap in all the MinusHP gear, I'd say "wait 1" would be the minimum you could safely get away with.
Personally though, I only cast T3 when I've run out of T4, so typically my HP is already in Sorc Ring latent area~
Alternatively, you could change the midcast delay from 3.0 to 1.5~2.0 and it should still work fine.
