Well, I would recommend it!
I am currently working on a Khalkin-Gol 1939 campaign, using Mixx's WONDERFUL new map of the area, and there I'm using it in many missions as a AI plane. (Below you can see them attacking the Soviet airfield at Buir!) The Ki-30/51 fills a BIG gap in any early war mission, as the JAAF, as you know, then relied quite heavy on light bombers of this type.


Now this is not meant as criticism to Skipper, as I am really happy to have this AI plane, but the the engine on the Ki-30 is too big, but the one labeled Ki-51 is actually a much better likeness to the real thing, so I use that one as my Ki-30! (As you see above.)
And Wingstrut: please, please PLEASE have a go at the Ki-51 Sonia when you have finished your Jake.
