I think one advantage of the Octocopter is that it is large enough to be controlled via IP over Satellite internet, which means it still works in GNSS & Radio denied environments. On the other hand, a drone with wings can also do that - provided it's not disabled by Elon for going too fast. So, have you considered making the carrier drone an aircraft style drone rather than a quad copter? Only one motor required, much more energy efficient, faster, longer range... or why not stick a model aircraft petrol or nitro engine on it?
