Huskblade-Dagger

Okay, I expect this is probably a weird question, but do you allow any leeway in terms of representing weapons?

I ask because for some reason I really adore the daggers used by Wyches and some of our sergeants. I'd really like to have one or two of my HQs armed with these, and I was wondering how much of a stretch you think it would be to call them Huskblades?

Put some scratches in to it and paint it a bone colour, and you are good to go! Most people wouldn't even mind if you just painted it as a normal blade. Go nuts!
