210 wasn't quite the death trap it's made out to be. It's not as "good" as the 110G but it has one thing the 110G doesn't: it was already being flight tested at the end of 1940.
While the engineers fought a bickering battle, actual combat pilots wanted it because it was better than the 110C/Ds it was replacing. It also wasn't too hard to handle for the experienced pilots at the time. Even so, the changes made that rectified the problems were mostly in place early on anyways. The tail was lenghtened and other changes were made by either the 200th or 300th airframe. The majority of 210s weren't as bad as the initial test flight on the first airframe, they just held the political stigma of all the bickering that was associated with it.
From an early war standpoint, the 210 would be awesome, handling issues and all. Much like the typh or tempest, the pros outweigh the cons.
I'd hope they add it as well, but won't hold my breath.
