Customize URL extension and @handle

Would it be possible to consider a custom URL for profile pages and @handle?

As a practical example, my brand page was created with a URL and handle that were automatically chosen for me. However, I have unified all my other social network profiles under the same URL extension and @handle, that is different than the one I got automatically assigned on primfeed.

It would be amazing for ease of use, and for customers, if they could also access my page and tag me using the same @handle they are used to on the other social network pages.
