A few other points of feedback for you too:
This feels like a rush deck in spirit because of the Oversight AI, since it's best early when the Runner can't break through something as big and mean as Tollbooth or Flare. That said, I think the prior feedback of trading in the two Closed Accounts for two more ICE like Wall of Static is very good. For the same reason, the advice of trading in Marked Accounts for Melange Mining Corp is also good - if you get one of these out early just for 2-3 turns behind an Oversight Tollbooth/Flare, it will go a long way to helping you rez more of your mean ICE.
If I assume you make the Marked Accounts->Melange change, then my additional advice to you would be to point out that you don't have a good way to make the Runner waste money by traveling down your remote into something unrewarding. That means every time they do manage to break through, they know they're going to get something good - either an agenda or Melange. That's not automatically bad; it just means that you have to pay attention to the tempo of when you put things into the remote.
Making the decision to do this does gain you something - you don't have to worry about which of your cards masquerade for which other ones when they are face-down in a remote. Normally, having a 5/3 agenda in a deck running Astroscript has some ramifications in this masquerading regard that you should consider as a deckbuilder. Since there's no way to trick the Runner into wasting money in your deck anyway (since I'm assuming that blowing up a Melange isn't a waste), then you don't need to worry about the fact that having 2 advancement counters on an agenda tells the Runner to come get the card. For that reason, I think your deck doesn't have a good reason to need to run 12 agenda cards in a 40 card deck. Furthermore, I think Priority Requisition is actually a great agenda in a 40 card deck that's running 3 Flares and 3 Tollbooths.
If you cut all 3 False Leads, 1 Breaking News, and 1 Project Beale, then put in 2 Priority Requisition, you gain several things here:
1) 3 card slots back for other cards
2) Easier combinations of points for you to score early to set up the win
3) Fewer clicks/credits/cards spent on obtaining your agenda points
4) opportunity for 8-9 bonus credits for rezzing ICE
For the same reasons, I'm personally of the opinion that you are going to want to try to score your early Project Beale agendas for 3 points as well. If you do the agenda mix that I suggest, you'll essentially have 3 3/2 agendas, 2 2/1 agendas, 2 5/3 agendas, and two that either serve as whichever you need worse at the time, 3/2 or 5/3 agendas. That's a SUPER powerful mix for always coming up with exactly 7 points to win and not having to ever overscore because of your agenda mix.
If you make the agenda mix change I propose, you can actually now put the 3 Marked Accounts back into your deck that I agreed you should remove earlier. I think that's a reasonable way to use those 3 slots - just put any of them you find out undefended and make the Runner trash them. This is a win-win scenario for a rush deck; either you get money or they lose money, and both of those are about equally powerful for you early on. The only thing you have to worry about is Bank Job. Normally, I don't give two @$^!s about someone Bank Jobbing my Marked Accounts; if you don't trash it, I still get to make money, and if you do trash it, you only came out a 1-2 credits ahead depending on how you count the install/run/draw for Bank Job itself. You do, however, have an extra element of danger in this. Without Oversight AI, I think "meh, now they can break my monster ICE once". With Oversight AI, this turns into "Uh oh... now they can trash my monster ICE". This is easy enough to work around - if you have an Oversight ICE that is currently keeping the Runner away from your agendas/Melange, just don't put the Marked Accounts in play yet against a Criminal deck.
The other thing you can consider doing is putting in 3 Enigmas (or sub one for the third Wall of Static). As already noted, this deck is ENORMOUSLY susceptible to Emergency Shutdown, and having these is a cheap way to help delay the inevitable shutdown shenanigans from Criminals for a couple turns.
Hope that helps!
