I def hear you on the Nintendo!! Everything else you mention needs to be reviewed and worked out thouroghly by a highly trained professional.......like a psycho therapist......I would like to weaponize the jeep. Bumpers that can shoot paintballs or ball bearings, smoke screen, ejector seat for when the wife gets bucky. Front mounted paintball gun for tagging prius the done yield to faster traffic. Maybe a way to drop catrips for tailgaters. Springloaded knee basher for wouldb jeep jackers
An underseat safe for my pistol.
Maybe an intergrated tech screens with hdmi and headphone ports for kiddos. Id mount a nintendo classic in there.
Def hear you on the sill guards!!Door detainer quick release.
Soft top storage bag.
Soft top opening/closing aids - perhaps as simple as a loop to pull on (for short people).
Wraparound sill guards
