Not jet, but I want to play here with the officio assassinorum suplement as a Eversor assassin. Of corse it is not allowed to ally a 30k army with a 40k dataslate but as long as it is fluffy and not to cheesy, it is no problem for the people I play against.
One idea, you could make rules for it using the "Malagra" Arcana and the right weapons.. Maybe also a relic?
Magos, Malagra, Cyber Familiar, Nanyte Blaster, Rad Grenades and master crafted powerfist/chainfist to represent the claw?
Lots of options!
