Is trivial to do but there's really no reason to do so. It doesn't make sense flavor wise and gameplay wise it would be better to let ZSS just spawn more armor.Samus can go to ZSS via a secret taunt, although ZSS cannot turn into Samus [and the dev team either doesn't want to make this possible or doesn't know how, as I've asked about it several times in various forms].
Charizard will probably be getting something similar to his Smash 4 side special (in terms of appearance, it'll probably be closer to the space animal illusions in functionality).Samus into ZSS with a taunt in Minus's mechanics is pretty pointless, though it's faithful to vBrawl at least in some form.
What's the plan for the down specials? I'd imagine Charizard's to be an extention of his side air, like Wario's up special designed differently.
