Not only the tier 5 Nord staves are a bit different than the draugr counterpart. Also the tier 5 Nord sword (The Master's Sword) has some little differences than its draugr counterpart.
Instead for Khajiit and Dro-M'Athra, on tier 5 Khajiit dagger still has little differences (the blade is a bit shorter and missing that blue pattern the Dro-M'Athra one has). On the other hand, the tier 5 axe is completely different.
