[Star Trek] Assuming I'm securely attached to the hull, can I ride the outside of a starship during warp flight? What would the effects on me be?

Suppose I'm firmly and comfortably mounted onto the hull of a starship using some sort of duranium couplings. I have an EV suit on. The ship jumps to warp 9. Do I have a reasonable expectation of surviving the trip? What  physiological effects would I experience?

As long as you're inside the warp field during the entire voyage, and you have a very solid method of attaching yourself to the hull, you'll be fine. 

Commander Tucker once experienced a warp field protected only by an EV suit, the combined warp bubbles of the Enterprise NX-01 and the Columbia NX-02, and a tow cable attaching both vessels. It was perilous, but he was fine. (The episode "Divergence", season 4)

And as we've seen in other disasters, crew members who are blown out of a ship when it suffers heavy damage at warp are physically intact until the moment they exit the warp field. (Star Trek Into Darkness)
