Trying to use Bullet Physics in new Game/Mod Project

[gokusuper5]

Hi there. I'm new to the forum and i'm trying to integrate Dynamic physics into the ID Tech 4 engine

The SDK for Doom 3, Quake 4 and Enemy Territory Quake Wars All have the basic Collision detection and ragdoll physics source code with them. I was wondering if there was a way to change and/or integrate the following into the SDK:

*Soft Body physics (for Flags, Hair and shirt sleeves, pants legs)
*Dynamic Destruction (i saw that you can "tear" soft body cloth when i compiled the demo maybe this can help)
*Cluster Soft body physics (For things like Sheet Metal and such)
*Deformation (For vehicles and such)
*Possibly : Dynamic Water physics(Dynamic water interaction) and Dynamic Particle physics (rocks dirt etc)

Tools:
*3DS Max 7/9
*Visual Studio 2008
*Doom 3/Quake 4/ Quake Wars SDK

A Design document should be up soon. I hope that this forum can help me accomplish this goal
