When Redline acquires a target lock, he uses two pairs of TL tokens. That means one spent to fire missiles and one left to spend on modifying dice results. With that in mind, Jonus is useless for him. Homing missiles are also useless for him.

Major Rhymer's favourite ordnance is advanced homing missiles. That's not to say other ordnance isn't useable on him, its just not taking full advantage of his pilot ability. Advanced Homing missiles (and even homing missiles) do not spend the TL (you just need to have it there), so again, their presence makes Jonus unnecessary. For that reason, I would look at replacing Jonus with something else and perhaps rethinking what ordnance Rhymer is bringing. Keep in mind that deadeye is very useful on Rhymer, since otherwise he cannot get target locks on higher PS ships...

Jonus doesn't do much for Redline, who will have an extra Target Lock. Proton Rockets are OK on Rhymer since he can stretch them to Range 2 and can fire it with Focus (rather than Target Lock) making higher PS targets easier to get a shot at. However, there are better options. I threw this together:

"Redline" (27)

+ Cluster Missiles (4)

+ Extra Munitions (2)

+ Fire-Control Systems (2)

Major Rhymer (26)

+ Advanced Homing Missiles (3)

+ Push the Limit (3)

+ Extra Munitions (2)

+ Twin Ion Engine Mk. II (1)

Omnicron Group Pilot (21)

+ Advanced Sensors (3)

+ Fleet Officer (3)

+ Ion Cannon (3)

Both these aces cost 35 points, meaning there's not necessarily a clear priority target for the opponent. "Redline" will have plenty of Target Locks for his Cluster Missiles thanks to Fire-Control System, and he has 2 of thanks to Extra Munitions.

Rhymer's best missile is probably AHM. He can hit someone at any range thanks to his ability. With PtL, he can make sure the shot is fully modified with TL and Focus both. Again, EM gives him a second, discounted copy. The improved Engine helps him get around after PtL.

With just 30 points left, I added a shuttle. The Advanced Sensors/Fleet Officer combos lets you pass out Foci and immediately do a green move to clear the stress. That helps Redline get better modified Clusters, and Rhymer is free to use Barrel Roll for one of his actions but still have both Focus and TL for his shot. The Ion Cannon can make enemies predictable for your ordnance deliveries.

that list is a lot of squish. It's going to go down in flames very quickly unless you trust your dice (and you shouldn't)

Redline and rhymer are both hilariously fragile and expensive glass-cannons that don't really stack well with one another. They hit hard (with the proper ordnance), but that means little when there are so many things out there that'll shoot before they do (higher PS)

here, they don't have anything to protect themselves (usually, a blocking mini-swarm does the trick) and they're also anemic with their ordnance (rhymer being all but worthless with only two a-homing missiles; making redline a very clear priority)

I don't think it's a type of list that'll end up working out reliably.
