Even freakier, I have done exactly the same conversion as well for exactly see the same reasons as pitcube. This justs begs to be converted this way!!! I hope they release a new Ragnar when they get round to updating space wolves. You can see my version at 98522 and at 51880.
This is scary!
this same mini rests for a few years in my "Special projects" half-painted.
As you did, i felt it needed a more dynamic pose (the minis of that time were all quite static, which diminishes their fierce nature, i think). i even repositioned the same leg!
So, of course i love your conversion and would beg you to improve on your armour painting.
Here a few highlights, coupled with a bit of blacklining/shading would boost your score somewhat i think. (though a 5,2 is serious understatement)
Happy painting!
