I doubt very many members of the non CD community will develop enthusiasm for any garment that would interfere with the convenience of being able to urinate without pulling your pants down. This would apply to any long pants, tights or hosiery/brief combination that didn't have a fly (or open crotch). There might eventually be some acceptance of a body suit style garment that was elastic enough to pull aside in the restroom, but even there, a structure similar to that used in old fashion tighty whities would probably improve acceptance.
