I don't think there could be such a thing as a bomber hanger queen (within reason). Performance isn't as critical with bombers, and besides most have about the same speed (the A-26 would be an exception). The Lanc has the clear advantage when it comes to bomb load, but you still see all kinds of bombers in the MA all the time. In fact, if you go via K+D as an approximation of usage rates (not as accurate with bombers as with fighters) the B24 actually is higher than the Lanc, and the difference between the least popular (Ju88, neglecting the A20) and the most (B24) is only about a factor of two. So I don't think the B25 would be any different and it wouldn't be a hanger queen.
Now with fighters, performance is critical, and there are lots of hanger queen fighters (Hurri I has about 1/23 the usage of the N1K2). The P39 might turn out to be a bit of a hanger queen in LW. However, it is hard to come up with WWII fighters that saw significant service and wouldn't be hanger queens for the simple fact that AH has such a large fraction of viable candidates already in the game. I count 74 aircraft in AH already- coming up with the 75th, and limiting yourself to only those that would get extensive MA usage, is near impossible.
