PCB for a Arcade Controller

Hi /r/DIY!

I want to attempt to build a controller similar to this one to play some rhythm games, specifically Project Diva and Taiko. \

I've found the components to build one, but have a problem. I need both thumbsticks to work for Project Diva F and F 2nd. The one i linked doesn't have any thumbsticks at all. Ideally i would like to use some small buttons to act as the thumbsticks. The game just needs to see the thumbstick "flick" in a direction but i have no idea if this is even possible.

I was looking into gutting a wired Xbox 360 controller but haven't found much info on how difficult it would be, or if it would be reliable. Any help would be appreciated. My PS3 has CFW so getting it to recognize the Xbox controller isn't an issue.

The parts i am looking at are:

Face Buttons x8

L and R Buttons x2

And the buttons for the "thumbsticks"

I was planning on using this PCB but it only has one joystick so it wouldn't work in this situation.

I'd like to keep the cost under 120 US dollars. I have the wood to contstruct the bocx for the controller, but can't figure out the component part of the equation.

Thanks for looking, and any help is appreciated!
