Hey, I've got a couple of suggestions if you're thinking of adding any (although the list is pretty long as is!):
In Production
IL114-300
Out of production, in service
BAe Jetstream 41
Production beginning 2021 EDIT - these should be in production approximately the same time as the MRJ, which is included so theoretically these should be too?
Irkut MC-21 (-200 & -300)
Comac C919
The rest are looking good and look to cover pretty much everything! (Apart from business jets which could be fun to see at some point but it's understandable if you don't want to add them)
