UnWeld&Thrust Tool

Hi there folks.

After beating I-War again, I’ve been trying to make the CNV 301 Dreadnaught ship.

PROBLEM: See http://www.youtube.com/watch?v=kw1m2ZW1u84&feature=related at 5:30 . After taking serious damage, the captain chooses to launch the bridge off the ship to hit the huge barricade-ship thing, sacrificing himself in the process. Would it be possible for someone to make a tool to do something like that with the spacebuild models? Un-weld and thrust the model forward, with limited control of the bridge?

Thank you.

Weld latch, thrusters, and a toggle button.
