Even though I've accumulated a lot of bits lately, I can't help with that.
Having had a look though I think I can feasibly pull off kitbashing a team based on the Outcast Dead book
Looks like they would be running as, wait for it... counts as Deathwatch. Mostly because of the weapons options flexibility. But also because Crusader Host blah blah..
That said, there's also the possibility of counts as Astra Militarum (Tempestus), throwing Janus, Pious and Espern from the BSF box in there and making it a Rogue Trader and his retinue. Annoyingly the Elucidian Starstriders list doesn't have much room for building your own RT party.
How long do I have available to faff with this?
