Strat mods

I have an Aria Strat, which I love, especially for the cost of what it is, but now using it as a modification or experimental guitar. Currently it has the built in pickups, but I have added in the Fender Mid Boost circuitry, similiar to whats found of Eric Clapton's guitar. I think the next thing I want to do is maybe add on a built in tremolo. Has anyone done this on a strat, or anyone have any thoughts?

Hi DB07, might help if you post some pics. So does it have a tremelo system currently or have the routes for one ?

It currently has a screw in tremolo bar if that helps.
