Default [Q] Change Home Button?

I have searched around and haven't seen anything about this yet...

I use swype primarily and occasionally have to hit the swype button (first one on the bottom row) to correct a word but I fat finger and hit the home button. This is a pain in the butt because when I use handcent in quick reply mode I lose everything that I write. My question is, is there a way to change the amount of time required to hit the home button before it actually goes home...or change the sensitivity maybe so I have to jam it?

Thanks guys
