More Weapon-specific finishers

The finisher animations on SM2 are absolutely phenomenal, and I particularly like the animations where the player's space marine uses their equipped melee weapon during the animation. I like them so much because the weapon choice being represented with the absolutely fantastic animation adds a lot of personality to your own character. This said, It is slightly disappointing that almost all of the finishers on higher-tier enemies don't involve the character's weapon. It would be really neat in my opinion to see that remedied, and of course get to see some more diabolically awesome finishers. I just wanna see my space marine beat the heck out of a carnifex with the thunder hammer. Thanks!
