I think using the original Morane (as depicted in the photos) as a Morko would be just a license stop-gap. The engine was changed to a Klimov (improving somewhat the performance) but, more important, the weapons were updated to 4 MG's in the wings and a German MG151/20 motorkanone (the Soviet UBS were used too), improving firepower and reliability.
The original Moranes, even outdated, were used, in decreasing numbers, until the end of the war. So, they can be used as they are. I feel very fortunate that devs are prioritizing historical accuracy, but without ruining gameplay.
