Sloan does have a big positive. He comes across pretty good on video. He could concentrate on producing videos for youtube and elsewhere. He’s got eccentric ideas on openings and other strategies but here, this works in his favor. Chess needs coverage of eccentric openings and not just more of the same old stuff. - Yet another video of the Najdorf Sicilian (for example)!
If he gets a director to coach him and line up shots, together with some post-production editing, he could make a name for himself – which is to say, he could re-brand himself in the chess world.
Conclusion: how Sloan could rehabilitate himself is an interesting exercise for a lazy afternoon.
