Tollbooth calls to me for the mid game. That constant money hit would hurt. And both Ichihara and Tollboth benefit nicely from Jinteki modifiers like Chum and Sensei.

Tollbooth is just too good to not include in this deck, but I wouldn't use it as the outermost ICE of a central server for JV2. It's best in a place where you want a Runner just stopped.

Trying to make a list…

Identity: Jinteki: Replicating Perfection
Size: 49 cards

Agendas: 9 cards
3 Braintrust - 6 agenda points
3 Nisei MK II - 6 agenda points
3 Priority Requisition - 9 agenda points

ICE: 24 cards
3 Chum
3 Data Mine
3 Neural Katana
3 Sensei
3 Wall of Thorns
3 Ichi 1.0 - 6 influence points
3 Pop-up Wndow - 3 influence points
3 Tollbooth - 6 influence points

Other: 16 cards
1 Akitaro Watanabe
3 Hedge Fund
3 PAD Campaign
3 Precognition
3 Private Contracts
3 Sunset

Boy… This is hard… 

I think you have too much Sensei in there. I find I only want one in a deck since it doesn't do much except add End Run to something else. Unless paired with specifc ice the general attitude in our group is "So what?". If they have an ice breaker that can get through the second ice then it's generally just one more credit to turn off the End Run statement.

Making that deck list made me realize that Jinteki V2 steers Jinteki towards making fortified servers rather than a deck that employs a "Door #1, Door #2, Door #3" strategy. Or at least I think it does.

Maybe try splashing in Viktor. Don't consider him an ETR ice, but instead a credit/click-sink with the addition of allowing the runner the opportunity to make risky runs by taking some early braindamage.
