There's really just one (new) vehicle design that I can justify: the iATM Carrier. 3xiATM12 and Nova CEWS w/ Ferro Lamellar.
There's not even that many Clan vehicles carrying ATMs. Just Mars, Zorya, and Stantovit variants among the Golden Century/older designs. And if they were converted to iATMs, only the Stantovit really has the speed to exploit specialty and HE munitions.
Later Spheroid Clan vehicle designs emerge with ATMs like the Balac and Hephaestus C, but that doesn't help the Society.
Among SLDF designs, the Rhino and Chaparral are the only dedicated missile carriers with obvious iATM conversion potential, but are again too slow.
However, the Kanga, with its LRM rack and SRM pack, would be a good candidate for mobile iATM platform. Maybe a plasma cannon could replace the AC. A jumping hover tank seems like the kind of disruptive, high-tech solution the Society would favor.
It's too bad there are no canon vehicle designs with Society toys. It's weird to field a trey consisting of one Septecemia, three Society protomechs, and seven SLDF tanks.
Some quad BA that could be piloted by non-Elementals would have been nifty, too.
FWIW...
