I don't really understand how the Foretellers' identities could be characters that don't act like them, don't have the same personalities as them, don't have the same voices as them, and don't have the same body shapes as them. If Ava was Kairi's Grandma, then Kairi's Grandma would be over 110 years old. And if she was brought to the time period of BBS using the same method as Ventus (and all the Foretellers assuming what you're saying is correct), then why would she be so much older than everyone else when everyone else wouldn't have aged? They obviously didn't all just wait and age for the time period of BBS. They got there using some fantastical means, such as the realm of sleep or time travel or body swapping or something. And Aeleus is way too calm and silent to be Aced. Aced is overly emotional and passionate and slightly dumb. The only similarities between Aced and Aeleus is that they're strong. Their chin shapes are also different. Aced's is more narrow. And all the other ones you mentioned just have complete different personalities, and like you said, are big stretches. If these were the same characters, then they would've been given the same voice actors/actresses and they would've been given the same personalities. I don't see why their personalities would have changed since.
I think the Foretellers' faces are more likely to look like characters we know or something, rather than the Foretellers actually being characters we already know. I'm still even iffy about that though too. Either their faces are kept hidden because their identities are being kept hidden from the audience or their faces are kept hidden because their faces are irrelevant because since their voices, body language, and gestures tell all we need to know about their characters and that they'll be irrelevant in the future of the series since they all just end up dying in the Keyblade War. Who knows though. It's hard to tell which of those is the answer.
