can we configure a mod to reduce the damage of DCA shots (ZILKA etc..)?

[shillum]

Hello, my friends and I love playing together on a private server but we would like to know 
if there is a way to make the DCA SHOTS a little less realistic... (yes I know it may seem a little strange) 
but we would just like to be able to sometimes take damage by necessarily having the plane which can no longer fly after 3 or 4 hits
without having to activate a cheat such as invicibility. 
the idea is to keep the DCA threatening but not so realistic to keep the fun side. Lowering the AI difficulty doesn't seem to be enough.

thanks in advance
