It's not optimized with way. You lost 2.5 sec (GCD after transpose) and you lost the "reduce Blizzard cost" because unlike you said it in the first msg, you only get the reduced cost if you cast a spell on the opposite buff. Casting blizzard 3 on Umbral 1-3 wont reduce anything.

Again, no. It's 10000000 times better to NEVER count on it. Get a gear with enough acc all the time.

On every BLM discussion on EVERY forum that I have found and from actual play, Transpose is better to go from Astral to Umbral. I wish I had P4 tooltips available to link to this post, but I dont.
If it turns out to be 2 dps better to do B3 than Transpose, Ill come back and change it.

Sometimes, you just cant get 100% acc. Its as simple as that. Unless you are in full on BiS gear or gear STRICTLY for ACC, you are not going to have exactly 100% hit. If you're doing dungeons, whether leveling or end game, or just farming and you are getting more resists than you'd like.. Grab it, use it, and move on.
