I think it makes sense for the Specter Damashii form to look so similar to the Ore Damashii, since the Specter Eyecon appears to just be an Ore Eyecon for Specter. They're probably the same thing, so similarities are to be expected.

I think it'll look even more different once we see the full suit, too. The patterns on his suit are different than on Ghost's, but we can't see that here. (except for the eye of course)

(Also we've seen Specter before, just off-color, so I'm not sure why people are surprised. And from what we've seen of Tutankhamen and Nobunaga, Specter's forms aren't going to be any less varied or interesting than Ghost's.)
