That would make bombers far too uber if they can take a gunboat shields in 1/2 hits... 4 paralyzers, 2 nova cannons would make quick ( yet very expensive) work of any capship...
And, I don't see why the gunboats would have a glitch to MISSILES only on their shields... but, I'm no mod maker, beta tester, but not much else. You still gota see the bigger balance issue though, you can't just say
" I WANT THIS BETTER BECAUSE IT SHOULD BE!"..
