I've played the PS2 versions of Silent Scope 2 and EX on my PC using PCsx2, with the joypad stick and buttons mapped to my mouse. I don't own an Aimtrak, but doesn't it basically operate in a similar fashion to a mouse?
If you're a big fan of Deadstorm Pirates, Time Crisis 4 and House of the Dead 4, I'd recommend picking up a cheap PS3 and some PS Moves with gun housings.
