I don't really know about the alternate names you selected... It doesn't look like you put much work into them, really. I suggest thinking of alternate words for that type and using them to make a new word instead of changing around the base word... Here's an example or two to show you what I mean.
FIRE type
Pyro = Fire
Pyran Type
WATER type
Water = Aqua
Aquav Type
See what I mean? I'm not offering these little names to you (even though I did come up with them in a millesecond) but I'm just showing you what I mean.
