Viewing sub repaints without game open?

Hey all, looked around and couldn't find anything close to what I'm looking for.

Is there a program out there, or even a possibility of having one made, where skin designers could open it to view the sub skins on what we've been working on without opening up SH3 where we can manipulate the viewing angles?
It's a pain in the keyster to open up SH3 twelve times in a row just to see how something looks after you've tweaked it a little bit.

With all these brilliant minds out there I hope there's such a thing.
