It's possible to make bras that don't rely on tension - Empriente does it - but they're insanely expensive at over $200 per bra. (Compared to 15-20 dollars at Target/Walmart or 60-100 at a decent boutique). There are still issues, though, because you need to consider that while a 30FF and a 38D are the same size in terms of tissue volume, the distribution of that tissue differs a lot. The wires need to be placed differently even if the same wire is used, so the wire itself would need to move which would be very difficult.
