Weiss Schnee
Chance: 60%. Ah, Weiss. The ice princess of team RWBY who takes her trope very literally. Like most of the cast of RWBY, she effortlessly lends herself to being playable in a fighting game - the series is famous for its fight scenes, after all. There's a tonne of potential for her in something like Multiversus.
It's a bit of a meme how often Weiss loses fights, but her powers are fun nonetheless!
I'll be honest: I think RWBY content is going to be more or less dependent on fan demand. The RWBY fandom is massive and, arguably more importantly, active. When WarnerMedia did a "March Madness"-style popularity contest on their Instagram earlier this year, Yang won - beating several characters already confirmed for Multiversus, including Ayra Stark, Harley Quinn, and even Bugs Bunny himself. I know this because Tony Huynh, the game director of Multiversus, tweeted about her victory. RWBY is nowhere close to the biggest IP in Warner's library by any means, but it has an active fandom and, if that turns into profits, I could see them continuing to add RWBY content past the already-pretty-likely Ruby Rose herself. Otherwise, I don't think Warner Bros suits would consider putting tonnes of RWBY content in the game to be a worthwhile venture.
While RWBY was spared from the mess that is Space Jam 2, it has had a few other notable crossovers with other Warner IPs. The most famous of these is probably RWBY's comic book crossover with the Justice League, which took a pretty unique approach to the crossover. Unlike most crossovers with DC I've mentioned previously, the RWBY collab didn't drop the RWBY cast into the existent DC multiverse, but instead re-imagined several iconic DC superheroes as they would appear in the RWBY setting of Remnant. This way you got stuff like Bruce Wayne being a bat faunus, Diana Prince being an automaton, and such... It's a very cool way of doing a crossover!
Na na na na na na na na na na na na na, RWBY! rwby.
Next up, Doctor Sleep, the sequel to Stephen King's The Shining, ran into a bit of a problem in its production. The Stephen King novel had an extended sequence where a character appears as one of her favourite characters from pop culture - Daenerys Targaryen from Game of Thrones. This reference was all well and good in the novel, but by the time the movie was being made... Well, there were two issues: (i) people really hated the final season of Game of Thrones and (ii) the character was being made into a woman of colour and many criticized Daenerys as being a sort of white savior character... So, they swapped out one WarnerMedia IP for another, replacing the references to Daenerys with Emerald from RWBY - apparently partly inspired by Kyliegh Curran being a real-life fan of the web-series.
As someone who did community theatre when I was younger, I do kind of relate to the excitement of getting a pop culture reference you actually like IRL into a project you are in...
RWBY has also had several video game collabs with other properties. This includes a handful of mobile games, the ill-fated fighting game BlazBlue Cross Tag Battle, and Smite, with RWBY setting the trend of that game getting collabs with non-mythological pop culture franchises (a trend since repeated with Avatar: The Last Airbender, Teenage Mutant Ninja Turtles, and, for some reason, the real-life metal band Slipknot).
With both Korra and Blake in the game, Smite has a corner on the "characters who cut their hair once beginning the arc wherein they come out as bisexual" market.
So... Yeah... I feel like Weiss is pretty plausible, but her odds will fluctuate wildly depending on what the fandom of Multiversus shakes out to be like once the game is actually out...
Want: 95%. I really like Weiss! When I played BBTAG actively, she and Yukiko were my go-to duo - a terrible decision because both were bottom-tier, but I had fun getting my once-in-a-blue-moon victories with them. She'd be super fun to have in the game. That said, if I'm ranking RWBY characters that I want in Multiversus, Weiss isn't in the S-tier for me.

Cinder Fall
Chance: 30%. Most of what I said about Weiss applies here too, really, but she's just further down the totem poll. As a very good, definitely-not-evil, I-see-nothing-evil-about-this-person supporting character, she doesn't exactly have the inherit appeal of a title character like Weiss.
RWBY Chibi: It's like if Teen Titans Go was consistently good!
As DanganZilla mentioned already, Cinder also got out-prioritized when it comes to definitely-not-evil characters in BBTAG, with Neo being added instead. I could see that being a risk again as... Frankly, there's just so many popular RWBY characters that it is just really hard to predict who they'd go with if they go past the main four - Neo, Penny, Qrow, Emerald, Nora, Oscar, etc... And that's assuming they get past the main four too...
Want: 70%. I mean, sure? I'd take Cinder. Cinder's a fun character with fun powers. Her interactions could be fun. That said, she definitely isn't on my personal most-wanted for the RWBY cast either.
