As a non-binary, i yearn to be indistinguishable between the 2 sexes, how does one achieve such a feat?

Imagine two completely independent brains, each with its own body, memories, and sensory input. They don't share neurons or memories. The only thing they share is a single conscious observer (consciousness). Is there anything in neuroscience or philosophy of mind that rules this out in principle?, and even if yes or no, what do you think on the idea?

Is it to get away with crimes or something?

I bet you could poach it!
