Implementation Note: Many of these extras could be designed as modular additions that attach to your existing truss structure or integrate with the open porch areas. The stabilizer attachment points might also serve as mounting locations for additional equipment. Consider which extras could be "plug-and-play" versus requiring more significant structural modifications during manufacturing.
