Hey Dante!
There are a few people (women, mostly) here who have had their work find out… I’d say, mixed results! However, it’s a little bit different when women are discovered than, I think, men being discovered. The stigma around women and pole dance is that it’s a sexual thing, and our society doesn’t like to admit that women can be sexual, and motherly, and professional… well, anyways! I’m not sure how a workplace would react to a man coming out as a pole dancer. Other gymnastics I could see being taken well (there are men doing gymnastics on the olympics, for goodness sake!), but pole has that “stripper” stigma still attached and hanging on.
As for dancing incognito, I would say that a mask might help a lot! Also, putting a lot of makeup around the eyes, distorting your features (making your eyes look bigger, or changing their shape, drawing attention to various parts of your face), playing around with shadow and lighting (also known as contouring) and colour, could all help to transform you on stage! Interestingly, drag queens are extremely good at this, and you could look up some ideas on Youtube. Getting a professional to do your makeup would also be a good one!
A good stage name also goes a long way to keeping your superhero identity separate from your secret, civilian identity 😉
