Other than Ad - Airforce gaps for the next time Iran should build higher quantities of shaheed drones especially the ones that fly higher like 6000m. Launching shaheed at 50-100m altitude would do nothing they can be brought down with ease by kalashnikov or even a lucky handgun shot.
At 6000m drone swarm and zig - zag maneuver when close to target cannot be taken down by anti-air gun defense. They can only be taken down by expensive sams like patriot or air to air engagement that would keep enemy airforce occupied. Shaheeds are not stealthy to modern radars.
Some newer variants might have some stealth features like Shaheed 238 but they will be much more effective and less detectable flying to target at 6000m altitude than flying at 50-100m altitude at which they can be shot down very easily and cheaply.
It all comes down to economics. They may go five times faster, but they cost five times more.
