Possible, but a lot of work and being "electrically minded" will not be sufficient. It's not done by just re-wiring the right cables you know.
The JagPad is a classical digital conrol. Each contact has a direct line to the interface and provides a high or a low depending on the status. It's read as a simple digital data port by the CPU (usually over a latch). The only exception is the numeric keypad which needs to be accessed by page switching.
To build an adatper to connect it to the PS3, you would need a microcontroller that reads in all the digital data (that's the easy part), maintains a USB connection to the PS3 as slave (that's already not so easy) and run the appropriate protocol to be accepted by the PS3 as a valid input device (most probably the hardest part).
I don't know if this protocol is undisclosed by Sony or whether it's only available to licensed suppliers.
Seriously, i doubt the number of potentially interested PS3 owners is sufficient to invest this amount of effort ...
