Bigger--not always better

In my continuing quest to degrade the potency of cap ships I wonder if
anyone has tried any of the following modifications to the rules and, if
so, how did they go?

1) Allow A Bats to only fire every OTHER turn.
2) Give a -1 to all to hit roles from A bats on cruiser class ships and
-2 on escort class ships.
3) Give a -1 to all hit roles from B bats on escort class ships.
4) Allow Pulse Torps to only fire every other (or third) turn.
5) Nova Cannons can only fire every third turn (still use the regular
charging rules).

I think these mods put the weapons in a bit better perspective
vis-à-vis their intended (designed for) targets.

Thanks,
Paul
