Sounds great!
I am still a fan of games like Falcon and B17II, which had a rather limited number or even a single aircraft modeled, but in very high detail and with a lot of dedication. Considering the incredible detail and the number of planes in BoB, I think your team already did an awesome job and I think it is the right thing to do for a long living simulation. And there are even more things ahead considering avionics, radar and stuff, as we read before.
I also find that a great part of the success of IL is exactly because of the things you said: This game is not about flying some planes against each other on an airquake-dogfight-server. It's to a large extend offline and coops, now, and considering we will have AI-planes and AI-Objects in Dogfight-Servers in BoB, these additional planes will be even more important for various missions to come.
