I'd use this chance when bombers stuff will change soon anyway and suggest giving them anti-cap bombs.
Something like much slower replacement of nukes, with much more punch. Like antimatter mines, very limited amount (5 only), maybe snac-like damage. Using them right should be risky for bomber pilot, but devastating if cap subsystems got hit.
Why this? Maybe cuz Novas are not cool for cap captains and might even be discontinued.
