Plugin replacing parts of CC with own code?

[strix]

I want make plugin to use same combat code no matter what CC is loaded.

How can i override Pull() and Combat() parts of CustomClass inside plugin?

EDIT:
Looking at Mr.Autofight i guessed overriding combat (and also completely achieving my goal for melees versus aggresive mobs) would be that:

public override void Pulse()
{
	while (Styx.Logic.BehaviorTree.TreeRoot.IsRunning && Me.Combat)
    {
		MyCombat();
	}
}

private void MyCombat()
{

}

But what to do to replace CC's Pull() for ranged classes?

And as we analized with friend, why this piece of code was even working? It should run as 2 independent threads without interaction along with CC.
