Arjac, 2 x Wolf Guard Terminators in LRC with EA/MM
Lukas, 5 x Blood Claws
LRC with EA/MM
13 total (5 Terminators and 8 in Powered Armor) in 2 LRCs. You could probably tinker with the WG wargear to make them more "characterful". It would be really fun against Horde Orks.
It also gives you a bunch of flexibility with putting heroes in either LR (all 4 HQ can fit in either one).
The 1850 version just switches out one LRC for a Drop Pod and adding some additional weapons and storm shields. In fact this list might even be more fun at 1850.
