Porting Oblivion models, easy Blender adjustment to Skyrim pose?

[KaptTorbjorn]

Is there some sort of simplified way of modifying an armour in the Oblivion pose (the T shaped with arms stretched out flat), to the Skyrim pose (with arms dropped down at the side?), I know there's an Oblivion skeleton/Skyrim pose, but the instructions for modifying it are for 3ds max, which I don't have.

 

Any help would be appreciated
