beast of slaanesh

I have this desire to get a bunch of Slaangors for my BoC army roster but I am really not liking one part of the design. The poses are formidable and menacing. The sculps are sublime. Everything fits. But THAT AXE! It feels so weird for a bunch of pretty crab boys to have a normal looking hand in which he holds an axe. And worst of all it's just a direct improvement in stats with one extra attack. I had this idea and have been sesrching online to see if anyone has come up with a way to keep the nice looking pincers but glue the axe onto one of the pincers and make it look good. Really need to visualise it to decide if it's cool or silly. Any help?
