SSB for Wii U Brawl Character Replacements Speculation

[Artisan]

So here's what I plan to go over:
Ivysaur was replaced by Mii Gunner
Snake was replaced by Villager/DHD for character balancing
Wolf was not put in the game because of Customs and the Fox/Falco variations are more different and would be accepted more.
Squirtle is obsolete and Pikachu is the main reason.

You can see where I'm going with this right? These characters were not in because there are either different variants of the earlier character and/or they aren't popular.
Similarities

• Mii Gunner Uair and Ivysaur Bullet Seed
• Mii Gunner Fair and Ivysaur Razor Leaf
• Mii Gunner Customs can be seen as Seed Bomb and Ivysaur wouldn't have reflector customs
• Momentum change aerials (MG Fair and Ivysaur Bair)
• Mii Gunner and Ivysaur have Laser Final Smashes
• Both characters would have about the same base speed (smallest Mii Gunner)
• Up B similarities between DHD/Villager/Snake
• DHD/Villager/Snake are projectile based characters, Snake just has better close range combat
• Villager tree and Snake mine
• DHD Can and Snake Grenades (Mii Gunner Grenades)
• Pikachu and Squirtle dair and bair similarities
• Customs are basically Wolf's specials

In short the character I could see returning is Squirtle but other than that there is enough similarities to please people who used characters that didn't return. But Squirtle could have a Waterfall that works like Pikachu's Thunder. But with the DLC some characters are variants of already playable characters so potentially all these characters could return as well as Pichu and Young Link.
