Wolvic sounds more natural to me than your other suggestions. If someone verbally told me about the project, my first guess would be to spell it as Wolvic. I can see possibly someone non native spelling it as Wulvic or Woolvic (if they heard the name in a conversation). I'm sure some may misspell it with an f also but if the project grows, it won't matter.
