Certainly. Beaufighter, A-26, He-111, and Ju-52 all have a higher place on my list than any Japanese aircraft.
You do realize that the Japanese plane set you just created is essentially bigger than the ENTIRE plane set we have in AH currently, right? (Maybe more around half to 3/4).
I would not oppose 1-2 Japanese aircraft (G4M would be fine), but they surely do not merit as many planes as you are proposing here. How would you like it if l said that we should have every single variant of every main American or European aircraft?
The Beaufighter and He-111 are needed, I'll give you that, as they'll both fill HUGE roles in scenarios.
HOWEVER, the A-26 is yet ANOTHER late-war American monster we don't have a pressing need for. It's not going to fill a role in the Mains that another aircraft doesn't already except for being a potential Perk ride. Its use in FSO/Scenarios/Snapshots would probably be limited as well. While the Ju-52 would be nice, it doesn't fill a role in the Main Arenas that the C-47 doesn't already and that's the ONLY place where it would really see usage. I've yet to fly in an FSO that utilized C-47s, and I don't recall seeing any scenario or snapshot setup involving them, either. And is base capture even ON in AvA? So the Ju-52 would be nice to have, but a German equivalent to the M8 would be far more useful for all facets of the game.
Also, just as an FYI there are 31 American aircraft currently in the game (32 if you count the Boston. If you want to stretch it and include the Brewster as well it will be 33 when the update comes out). Assuming HTC would add everything, the second list I posted above would bring the Japanese plane set to just above that. And sure, some of these could be trimmed. Like instead of the two Ki-44 variants I listed that could be handled with something as simple as a gun package option in the hangar (which if you include the P-39D's 20mm option, technically means we ALSO have the P-400. Our F4F-4 has a 4x .50cal package which technically makes her an F4F-3, bringing the American plane set up to "35").
