What is the best way to rebrand Upfront (white labeling)

I have been debating whether or not to use beaver builder or upfront for our new vertical site marketing. I think Beaver Builder may be good in the short-term but it's hard to bet against WPMU.

So here's my question...

I want to white label the themes and Upfront. Is that possible (white labeling). I noticed the loading icon in admin shows "Upfront" etc. Beaver Builders offers a complete white label solution and if WPMU can give me that, I would like to keep this project "at home".
