New York architect Esther Sperber has been thinking about he problem. The solution she has arrived at is architectural in nature: Bathrooms By Size

Sperber suggests that labeling restrooms by size, as opposed to gender, would eliminate the arguments favoring “bathroom bills” like North Carolina’s House Bill 2, which effectively prohibit transgender people from using public facilities that correspond with the gender identity.
