What's wrong with Engetsu being a fire-type zanpakuto? The kanji for Engetsu is 剡月. If you break down the characters of this, 剡 is a combination of 炎 and 剣. Which would reference "flame sword". Although the meaning for Engetsu is different, 炎 is flame and the other half of the kanji 剣 is part of the radical for sword.

I'm actually starting to think Getsuga Tensho was original to Ichigo alone. Then, Isshin somehow taught himself to perform it, too. After all, GT is little more than a reiatsu wave produced by swinging a sword. Even Kenpachi is capable of doing that (remember how he cut the nearby building in half when he took his eyepatch off during his fight with Ichigo).
