If Geno can't be a full-on fighter, I'd be very happy with his costume if it got the Sans treatment. The costume in Sm4sh was so freaking ugly, man. As long as it looked like Geno, I'd be sold. Bonus points for some music, too.
Was it really ugly? :s i remember it being one of the most good looking ones (K rool and isabelle on the other hand were hideous) and i remember mii gunner moveset translating pretty well to what geno would do (unlike say, Skull kid and Ashley)
I really think that i would be very happy with mii costumes representation for characters that otherwise wouldnt stand a chance, as long as they did certain changes to how mii costumes work. My biggest issue obviusly is proportions. which is obviously the hardest to change. but i think that 3 fixed Heights/proportions would actually still be manageable, as it wouldnt be as bad as just creating 6 echoes balance wise.
The height difference doesn't even really needs to be that big and to manage different proportions i don't think it would be a problem to just upsize or downsize the head. smash prioritize gameplay over proportions and is not afraid of doing inconsistent proportions even in teh same series (put link and young link next to each other and you can see hor different their proportions are, and how big is young link)
Normal would be teh actual proportions that work pretty well for characters like Skull kid, Knuckles and even Isaac and some Final Fantasy characters when you want to replicate more teh sprite based designs.
Another proportion slightly taller, slightly bigger hurtbox, slightly longer reach and smaller head would work wonders for all the manga/comic/realistic characters, Black knight, Dunban and takamaru costumes would really benefit from this, and you can use them to add carthe blancha to fire emblem characters, Final fantasy characters, etc etc etc...
Also a shorter and bigger headed proportions like what we had before would fit more cartoony mascots, like goemon, Ashley or even Geno or other future potential additions like jack frost, bomberman, etc....
Second Customizable taunts, and costumes being sold with a costume designed taunt in order to inject a little more flavour to the otherwise dry MII moveset also would do wonders in order to make you feel like you are using your desired character...
Finally, I really want a mii Caster/wizard/Spellslinger character. An easy way to differentiate itself from swordsman and gunner is giving also a resource management mechanic similar to robin or hero's magic... I would love playing with Ashley, but if they give me a wizard ashley i think i would be happy with the costume. Same with Stuff like Black mage from final fantasy
Oh, and masks... instead of tehatrocities that are Krool, Tails and isabelle costumes
