Sure, if you do made-to-measure or bespoke, you can make the determination what looks better on you and ask the suit maker to open or close the quarters. On RTW, that will be pre-determined by the brand/model of the suit. Some jacket quarters are more open while others are, by default, more closed. I'm not sure if you're suggesting that a pear shaped bottom would cause the quarters to open more, but I would imagine, that if were the case, the jacket wouldn't be draping properly and isn't cut well for your body type. But whether quarters are open or closed is based on how it's cut, not what the person's body does to the jacket, if that makes sense.
