I tried replicating their glow effect but since Oblivion do this in a very weird way, they cannot look exactly like in Guild Wars. Also, you absolutely need to have your HDR enabled to have them glow at all.
In Oblivion, axe are blunt weapon for some reason. At least the few I checked in the CS were blunt. In Guild wars, axes are slashing weapons so I made those One Hand blade instead of One Hand Blunt.
You will need Blade skill instead of Blunt. Changing them would be pretty easy if your really need to. To do so, open the CS, go to File > Data, put a check mark next to Chaos Axes.esp and click Set as Active File, then click ok and go to Items > weapon in Object window. All the axes should be on top, double click each of them one by one and change OneHandBlade to OneHandBlunt. Save and exit. Voila!
I put them in a chest in the testinghall. You can see exactly where on this image:
