Perhaps more focussed on a specific sport than you would prefer, nonetheless, a well constructed but affordable archery bag would go a long way for those in the sport. Bows that break down into a handle "riser" and 2 "limbs" also have accessories like removable sights, equalizer bar (~ 2' long x 3/4"), and more. Even a decent student bow can start around $400. Protective padding with secure slots or pockets for bow-parts (one size CAN fit all), pockets for accessories, and storage for arrows would be ideal. The available straps would work a treat!
