Really excited to be getting my new computer in the next 2-3 weeks, skyrim is #1 on my list of games to get. 
That is siiiiiiiiiick. Can't wait to start making my own weapons.

I haven't modded Skyrim in awhile, but it is a PITA to get stuff in....hopefully they will have the new scripts for blender to read the Skyrim nif files....
when I did the weapons( I was trying to add animals also) you needed to use a couple different programs to convert the Skyrim files so Blender could read them...and it never worked out to be "easy"

I wanted to add for the OP
the vanilla version of Skyrim is kinda cheesy....I mean cmon man there is no way in hell a guy with a sword is gonna kill a 90 foot fire breathing dragon....
my suggestion is to grab some mods that make it more realistic...."Deadly Dragons" is almost an absolute must.....
once you install that mod......I suggest you DO NOT try to fight the 90' flying.... fire breathing Dragon....
