Although I don't know much about the specifics of Heavy Gear, I'd also use at least a good portion of ablative DR. Did this once in a GURPS Starcraft campaign and it worked quite good.

Though you're right that the loss of armor, is not "real damage" yet.
Basically I'd try making it possible to destroy secondary systems like sensors more easily!
The classic idea would be something like: "The missile hits your vehicle and blows up a part of your front armor. Apparently the optical sensors on the front are also damaged by this attack, though your radar system is still working."

A possible option would be something like "Surge" from Powers p102, a weapon enhancement that forces damaged electronic systems to make HT checks against malfunctions or generally an Affliction Attack against electrical systems...

And/or the systems that could likely be damaged, e.g. the Hyperspectral Vision advantage as a sensor array, could be bought with something like the "Breakable"-limitation...
