besides shadow, what is your roster for the next smash bros?

i know how to play as shadow and silver in ssbb, itz a hard glitch to get

I would add Vector and the koopalings. FS= Final Smash
Vector's FS: he would turn into a giant dragon and it would almost be like Yoshi's but adding a Genie Sonic twist. He fires fireballs at whoever is in front of them and have tons of punches then a crash into the ground maybe some bites and that's it.
For the koopalings while I was reading each one's power, they shall use their own power like Lemmy's power of ice to control the stage almost like Lucas's and Ness's but for ex. Lemmy, giant ice comets are flying out with bombs inside.
