Out of curiosity, let's say that the ARMS character is Max Brass, or Dr. Coyle, or Helix, or someone whose inclusion heavily implies that being an assist trophy or a spirit is enough to disqualify someone from DLC. What would your ideal Fighters Pass 2 look like in that case?
This would be mine:

Admittedly, it doesn't seem overly likely for a variety of reasons (given how rarely Smash has added characters from M-rated games (
), it seems unlikely that they're going to more-than-double that amount), but it's my ideal list, not an attempt at a prediction. (because I'm well aware that I'd be way off if I tried predicting, considering that I thought Erdrick would be the default if we got a Dragon Quest hero, that Banjo and Kazooie were never going to happen despite wanting them to be in Smash since the first Smash game came out, and that we wouldn't get Terry until further down the line until the Nintendo of Europe leak happened)
I put Doomguy last because, ideally, the development team would have learned to not save a combo-heavy character like Dante or 2B until the end so there's more time to balance them. (the order of the others doesn't particularly matter)
Admittedly, I haven't played much of Tekken or Nier Automata, but it seems like those characters have a ton of material to work with for moves, on top of everything else that they'd bring to Smash Bros (stages, music, spirits - the whole shebang). Heihachi's got a ton of history behind him, and it's pretty rare (in games, at least) for a villain to be the face of the franchise.
As for 2B, I'm sure some will say that she doesn't have a presence on Nintendo consoles, but considering that characters like Cloud and Joker had a presence on Nintendo consoles that could generously be called "minimal" at the time of their announcement (Cloud had a few cameos, mostly in Kingdom Hearts games, and Joker had a 3DS spin-off that released in Japan about a week before his announcement), I doubt that would be an issue. (plus, the movesets made by
@Venus of the Desert Bloom for
2B and
@JudgeHeihachi for
Heihachi helped to convince me, or at least made it much easier for me to picture them in Smash)
