Those are all awesome helicopters.
I’d love to see the Alouette III and Lama in Aerofly for iOS
I would suggest some non-tail rotor helicopters. First, the German Flettner Kolibri. The instrument panel is simple, so the functions of the interactive cockpit can be easily programmed.
Edit:
The view from the Kolibri is excellent due to the open cockpit, it would be a pleasure to fly it. It would also be nice if this simulator included the only airworthy copy of the Kolibri in the world. 
Or perhaps the successor of the Kolibri, the Kaman K-MAX with a similar system.
The coaxial Kamov Ka-26 is also interesting.
Either the Chinook with two main rotors, or the similar Yak-24.
Or the or the almost helicopter Osprey.
Although she is not a helicopter, she can hovering too.
I vote for AH64, CH47 and CH53!
I would love the Osprey.
Chinook would be great, but I would love to see more liveries on the EC135
