I really doubt it. Oka is a stalker but not a killer by any means. You can tell by her personality and the way she reacts to murder taking place in front of her - She has never even seen a corpse. I'd even go furhter can call her and her club "occult-wannabes". They do these rituals that do nothing and tell people they are very interested in the dead but when the actually see that sort of stuff they get freaked out. There's no way Oka would ever get actual blood on her.

Oka is also not a computer nerd. She does have a computer (like virtually everone) but these days everyone knows how to use Google. Oka does not seem to have any special attracion towards computers. Other than the only real candidate for the daughter (Info-chan) the only girl computer nerd is Pippi and I seriously doubt her being anything more than a minor NPC.

Then there is the final and strongest argument against Oka being the daughter - It doesn't fit in the plot. The journalist and the past are a major background plot and therefore the true nature of the daughter will probably only be revealed at the end of the game. Back in the days of the first intro, Info-chan was supposed to be the last rival, which fits perfetly, but that is now obsolete. We have all speculated that the daughter will be the last rival, specifically the SCP (who is now known as Megami) but this had also proven to be false since we already know who's Megami's father (the CEO of Saiko corp). The only conclusion is that the daughter is not a rival at all, and Info-chan still fits perfectly. I believe that the game will not end immediately after defeating Megami. Instead Ayano will still face Info-chan. Even though she will not be a real rival (she does not have a crush on Senpai), she will want to hurt Ayano as pure vengeance for what Ryoba did to her father.
