Squid, Blink! The ability to vanish for a second and wind up facing enemy engines.
Junker, one free death, the ability to rebuild the ship from.its own debree, giving it an extra life before respawning normally.
Galleon, intimidate! If your ship has arcs on the enemy ship, the enemy get scared and their crews trousers all turn brown.
Mobula, upside down weapons. All weapons can be turned upside down for a limited time l, allowing Artemis to shoot up and carronade to shoot down as example.

On a serious note: Honestly I think Logic hit the nail on the head, unless the abilities were super cheesy it'd just end up being a number buff.
