英語版FF9日誌99 : Even if she were to command an army of black mages,

 前回と同じ会話からです。

Dagger:

At the Village of Dali, we saw numerous black mages. They looked like golems, controlled by some powerful magic. On top of that, they were being created under Alexandria's supervision. I don't know how they're related to Vivi, but if Mother is planning to use them for war...

Regent Cid:

We won't let that happen. Even if she were to command an army of black mages, she won't make a move as long as we have our airship fleet. Don't worry <gwok-gwok>. Everything will be fine.

Dagger:

I'm so sorry, Uncle.

Regent Cid:

Now, now, come on. Don't be so formal. I'm helping you because I am your Uncle Cid, not because I am the regent of Lindblum.

Dagger:

Thank you so much.

Even if she were to command an army of black mages, she won't make a move as long as we have our airship fleet.

以前、if S should～で「万一～したとすれば」という確率の低い仮定を表現していましたが、この文章のif she were to～もそれに似た意味になります。

ただ、shouldの方は話者が、確率が低いとはいえ起こりうると思っているのに対し、were toの方は、起こらないと思っているニュアンスになっています。

「もし、彼女が黒魔導士の軍団を指揮することがあったとしても、我々の飛行船艦隊があるかぎり動くことはできない」

と言ってはいますが、そもそも黒魔導士の軍団なんて使ったりしないだろうと思ってるわけです。
