In short, you can start a charity and pay yourself a salary from the charity. There are all sorts of charities paying large salaries to their directors.

I would say, good luck getting people to donate to your charity given that you will be anonymously taking a salary in order to profit from the activity. Typically, large donors will want to know what percentage of their donation will go toward the charitable activity and what percentage goes to admin costs. Trying to remain in the shadows while getting people to give you money will be difficult.
