[UF_Shoki]

To my opinion, the most needed ones which are terribly missing to have some interesting missions are :
Ki-51 Sonia (widely used through all campaigns
Ki-48 Lilly (same as above)
D4Y-1/3 Judy, used starting 1942 as a recon plane and widely by mid-1943 as a dive bomber to replace the D3A Val
Ki-45 Nick (but I've seen someone already working on it for the last versions)
Ki-44 Tojo (same as above)
G3M Nell, widely used since early 1943 as a complement bomber along with the G4M. Widely used in China, in the Singapour and NEI campaign and early stages of Philippines and Salomons campaigns in 1942.
F1M Pete, waidely used in all theatre, especially in NEI and South Pacific theatres
C6N Myrt, used by 1944-45 as a swift recon plane (very few intercepted).


By the way, I guess that any recon "flyable" plane should have a bomb sight "station" to be abble to take pictures of the target
