Sinking Jump Pak into controller?

[specfo]

Was wondering has anyone attempted this, perhaps sinking the jump pak into the controller so it doesn't stick out? I've seen all the xbox joystick/button mods and figure there could be other things done to the controller? I've googled and havn't really come across anything im thinking about doing (unless i did a poor job at searching) Any info would help, as i'll be ordering the things i need to attempt this. Thanks.
