I know there are already a few Dragonborn body mods available but I was curious if it would be possible to use what I believe is Body Type 4, Halsin's body type, for Dragonborn? The current Dragonborn body mods aren't exactly what I'm looking for but Halsin's body type is just right so I was wondering if anybody could do it or how easy it would be for me to do myself? If so how could/would I go about doing that? Thanks.

I want to start off by saying that I have no experience modding and that this is the first time I've tried anything of this type. Anyways I'm trying to create a specific body type for my character but no matter what I do within NifSkope I can't the changes to appear in game. I've been editing existing mods that are close to what I'm looking for, but like I said before can't get the changes to stick. I found this thread when I did a Google search regarding the problem I was having... http://forums.nexusmods.com/index.php?/topic/650111-nifskope-to-skyrim-not-working/ ...but it didn't solve my problem or maybe I'm just not doing it right. The attached image shows what I'm going for. In the top half image I've used blue to illustrate what I'm looking for and the red as the problems or what I really want to change the most. The bottom half the image shows the mesh I started with on the left and what I morphed it into on the right. I'm sure the arms are bigger than what I'm wanting but I thought it was a good place to start. I'm basically trying to make a "super hero" body type, ie wide shoulders, V shaped torso, etc. The RaceMenu mod allowed me to adjust the character biceps to where I wanted (which was awesome) but I'd like the shoulders, forearms, and hands to be bigger to better fit the "cartoonish" proportions I'm going for. I also want to raise the shoulders up a bit too. Thank you.
