Here's an idea I had a few days ago: have custom-made armor for a dracoform, as seen in Eragon and other such movies/books with dragons that have armor. Blend the Vehicle Armor rules in with character armor.
Such as: You can only have an amount of Dragon Armor equal to twice your Body or 20, whichever is lower, and if your Dragon Armor is greater than your Body, your Run/Walk speed is reduced 20%. Also, use the Maximum Armor Modifications guidelines layed out in Arsenal, page 44 for the Dragon Armor, but allow Weapon Mounts on the armor (taking up as many modification rating points equal to the number of modification slots it would have taken in a vehicle).
Also, allow it to stack with the dragon's natural Hardened Armor (similar to Trolls and what-have-you). IE: a Drake character with Dragon Armor 6 would have Hardened Armor 10, and it would be able to support Nonconductivity 4, Chemical Protection 2, a commlink, and a microphone (so he can hear/talk through the 'link), but no more modifications.
This is especially useful to Drake characters, but Dragon NPCs would (in my opinion) also get a lot of "mileage" out of this as well.
