Wow. When I saw your roster, I took it as a troll roster but you are actually supporting it. Sakurai has said there will be less of a focus on the roster and that, in SSBB, he felt the roster was complete. I think we can expect to see some cuts. Please note: some.
In no way, shape, or form will we see such massive cuts as you proposed. Really. Yoshi, Bowser, Peach, Zelda, Ganondorf, Captain Falcon, Ness, etc while proposing to fill them with even minor characters such as Rosalina, Ghirahim, and Toon Zelda? That would be idiotic at best.
And then you add characters like Bayonette, the Wonderful 101, Yoshimitsu, Virtualboy, and Plusle and Minun? Those are the ridiculous characters that SSBF mentioned. They have next to no chance in appearing. P and M has the most out of them all.
You can be radical in your roster design but if you truly think this is a possibility, you lost all you credibility. It's laughable. People were furious when the Melee characters were cut. If Sakurai was stupid enough make such massive cuts, the game would hardly sell because they eliminated much of the players favorite characters. You obviously have no idea how Smash fans think or react.
And yes....the roster is just a part of the game but it's a massive part. People play as characters they enjoy. For example, I main Zelda because I like her. I'd be pretty pissed if she was axed despite her importance to the Smash franchise and Zelda. And while I don't like Bowser too much, axing him would be a crime.
It may be "cool" to be radical and different, you really lost any credibility you had with that roster. Just sayin'.
