Nah, too complicated. It'll never catch on.
Maybe it'd be worth the two of you properly getting your heads together and presenting this wild and revolutionary idea to one of the manufacturers? You might get escorted out of the building in tight fitting garments and safely and discreetly homed. Or they might just take it seriously and give it a go?
