If you wait until Tacit has its flight pack and you guys figure out more Raubtier stuff, you could probably make some bionic ornithopter/rocket drones that can enhance Tacit's airborne manoeuvrability while attached, a la the mini-Angels attached to Kaworu's Trident Warborn (more S&WH40K references, yes, but it's got some good stuff to consider). When detached, they'd basically be heavy assault helicopters (well, ornithopters), probably with a Micro Laser Vulcan each.
Keep in mind that, with Fangs, you're going to need a place to put them while attached. For example, the Waffhund Fangs could probably mount one on each of Jagdhund's thighs, below the scabbard, and maybe a third on the back skirt armour. Phenom doesn't have much on his back, so that's viable. And Tacit's shoulders are free, so you could have some Fangs hanging off there.
