Also, If it procs you can switch targets and throw the TP at another target. I'm far from a good BLM, but it sounds like a good idea to me in my own head lol.
You can, but it's a straight up DPS loss and can still mess with your mana. As you may get an extra tick.
We're talking like tenths of a second here. You don't need to wait for the tick, you need to wait just enough so the tick happens during your F3 cast.

Remember the AoE rotation is F3-F2-F2-F2-Flare-Transpose-F3-F2-F2-Flare. Adding in a T1 to force the tick or something is a pretty big DPS loss. Not as big as having the wrong amount of MP in AF but it's definitely not optimal. On 3+ enemies every single target spell is a DPS loss compared to F2/Flare, even T3P.
Also you don't need to cast B1/B2 in the AoE rotation ever.
