Transmogging artifact weapons?

I wonder if we will be able to transmog them. I mean, not using them to transmog other weapons, but using other weapons to transmog them. If will be weird weird everyone using the same weapons. Yes, there are customizations but seem limited.

I didn't find the right solution from the Internet.
