But giving Miis a personality would completely defeat the purpose. The whole point of Miis is to insert the player into the game.
But mind you, Smash doesn't play by those rules. It isn't exactly one to follow canon.
If they could give PKMN Trainer and Villager, two characters that exist for the exact same purpose a character.
They can find a way with Miis.

Substitution
That's an alright move idea, albeit a tad similar to Diddy's UpSpec for my liking. Thing is, picking out single unique moves doesn't do anything for me. I like to see how multiple unique moves come together to form a unique playstyle, which the Mii is simply incapable of providing by spamming props. It's partly why I dislike the WFT; her playstyle is just a generic balanced rushdown one from what we've seen thus far.
I can help here as well.
See, we have bit and peices that can come together to make a moveset.
Not only the numerous Mii games that are out, but something else.
See, Mii is supposed to represent the Wii correct? Well, why not let him use Wii accessories in his moveset?
Like having a "punch-punch-uppercut" combo using the Wiimote+Nunchuk?
Or having the Dash Attack use the Wii Wheel (like he's stopping an invisible car)?
Or having his Neutral Special use the Wii Zapper is some way?
Side Special?
We can let the Mii use the Home Button on a Wiimote to "pause" the area in front of him.
Temporarily freezing opponents/projectiles/items in from of him.
Though, with great power comes low batteries.
And thus this attack requires charging (and the shorter you wait, the weaker the attack).
