Has anybody seen Imperial Agents armies, the Rogue Trader detachment in particular, in action? I'm curious if with some kitbashing (or straight up proxing heresy solar auxilia) you could make it into a fun or at least functioning army at anything above minimal point limit.

I like the basic rogue trader and navy infantry and could squeeze in a deathwatch marine squad as some marines on lease from their chapter, but they really lack proper tanks and long range firepower.
