Yeah, it was. Check this out: Meet what I call Tahonua, Toa of double Vahis. This was concept art of the Vahi before Bionicle was released. So was there going to be a, I don't know, Toa of Time Judging by the fact that he has an Onua claw and a Tahu flame sword... I'm pretty sure this is just a concept. But do you know what was more likely to happen than a Toa of Time? DooHeads. All I can say is I'm glad they never went with the Vahi as a main mask. Looks rubbish when worn. Well... depends on what head color you use, and if it goes well with the eyes and body colors... it actually looks really cool on certain MOCs. Oh, I'm sure it could be done. I just think it's too bottom-heavy for a figure as sparse as a Mata or Nuva.
