i think that points of conflict would depend on whether the Scoprions get too close to the Seafox held worlds within the cluster proper.
and as far as the equipment.. we know that they can't build their own mechs. my guess is that native production levels for vehicles, fighters, and etc would be at age of war tech. and you could probably use the canon age of war tanks and such to fill their forces out. with perhaps a few rare succession wars tech units leftover from when it was in the RWR or obtained via trade.
i also suspect that the Sharkfoxes, who have set up their holdings there as major industrial sites, are making a killing selling equipment to the locals. i could see them loading cheap IS surplus into ships heading back to the cluster, selling said IS surplus at premium prices to the locals, then loading the ships up with clantech goodies to ship back to the IS for sale there.
