Do you mind if I make a few suggestions? First of all, your choice for the enemies seem kind of lazy, just saying. An Octorok is much more fitting a replacement for the Goomba than Mr. Electric Dancing Pickle Man. Plus, Goomba's do in fact change sprites when turning around so the Octorok wouldn't be forced to just crabwalk all the time. Also, a good replacement for the Koopa would probably be either the beetles you kill by pushing off the edge in LttP or the tektites or whatever generic bugs which hide under blocks, stones and bushes, or maybe something else. And is that Vire as the paragoomba? Kind of an odd pick for a character with an actual name, I guess, and Tektites would be a much better fit, seeing as the paragoombas in SMWar don't actually fly, they just hop. Though I do like the idea of a Triforce piece as the star/shine/ztar.
Oh and for other modes, perhaps the Master Key and a Wallmaster for Phanto?
