Chaos lord with Mark of Slaanesh, do these stack?

[Alucard Hellfire]

I was wondering if I have a lord of chaos on foot with a mark of slaanesh as my general, can I stack his "Reaperblade", with "into the fray"(Godseakers ability) and "Euphoric Killers" (slaanesh command trait) to auto hit with a 6, doubling the hits causing 4d6 wounds on his first attack of the game? 

[Drib]

Yes, you get 2 Hits with 2D6 Damage. Keep in mind to do wound and save rolls for both.

[Trav]

Yeah this is heaps of fun, if you make both wound rolls

It is very swingy.  Started with 2 0dmg games and a 3 dmg game to start off the testing, followed by nearly killing a verminlord.  It is a lot of fun though.
