Well, if you get your hands on some rare clan-grade Ferro Lamellor, you might survive a bit better.
Still, there's no way to get this thing fast.
I'd vote for making it 5 tons lighter, it can't really drop your defense by much given the engine efficiency.
The AC 10 probably does a better job as an LBX, lighter, more range, more options.
Leaves you sufficient weight for some missiles and a case system.
Also, where the hell are you getting that much FL armour? You might buy enough to outfit a lance of hovercrafts, but this thing?
