Without coding? Nope. Blur requires coding as well, and quite a bit of it. And you're right about the animations, that's just how it works, there's no dynamic posing of the hands. What's worse, the animation is shared between all (or at least most) of the weapons, so you can't just change it for that one (without coding). And in my opinion that's clearly not acceptable for hosting on JKHub, I find any use of existing models/textures beyond getting the dimensions of your recreation right questionable. (And you may even get in trouble for a complete recreation due to Intellectual Property rights... but it's a good deal less likely, especially with small mods.)
