You might enjoy special events, doesn't the 68th fly in the Friday Squad Ops?
So, as has been mentioned, I don't understand why you would remove planes that are already modeled. So far as I can tell, there is no limit to the number of planes that can be modled, so this isn't a zero-sum equation.
When AH2 goes live, we'll be getting Events going again. You should give them a try. They can really put those useless planes in their native situations (or at least closer to it than the MA), and bring out the marvel of it all.
Hell, my absolute favorite flight ever in AH was in a freaking SBD in the Coral Sea Squad Ops in July 2002.
Anyhow, to reiterate, removing planes that are already modeled shouldn't have any effect in how many new planes will be added.
