Here's hoping we see your ideas implemented Strike.
As for the radios in particular, i'd really like it if we at one point could have a realistic depiction of radio comms from that era with some sort of built-in voice comms module.
Tune the correct frequencies or preset them before take-off in the load-out/aircraft selection screens, since fighter pilots usually couldn't adjust them in flight (they just had their ground crew set 3-4 presets and switched between those, radios were heavy and cumbersome back then so they had to simplify things...no transistors yet! bombers usually had full radio functionality though), a bit of static maybe thrown in over our voices and most of all, a realistic reception/transmission range.
I don't know if we'll get something like this, but in the Br.20 there's a radio operator's station modeled with some controls, maybe it's a sign of things to come
