If you mean appearances, then you can transmog your artifact to other appearances from the wardrobe collection.
There will be some who are using the more recognisable appearances, such as doomhammer simply because "IT's DOOMHAMMER !!!!".
But there will be plenty of others, myself included who see the wardrobe as an opportunity to use looks we would have overlooked previously, or even weren't aware we had access to.
Admittedly so far I have not been creative with transmogs, in part due to me being somewhat of a hoarder of "novelty" stuff, so not having the inventory space to really cater to that experimentation.
That is something I will have the option to do in the future.
The only issue there is the fixed weapon type.
A caster using a staff for instance in their current appearance would be prevented if their weapon changes to a main and off-hand, which you cannot do anything to change.
That fixed weapon type of the artifact will forcefully break some weapon transmogs unfortunately.
