Not sure if the E190 is ready for production, but there are a number of them currently flying in Australia that haven't been done yet. Just thought I'd list some of them if there's any interest in doing them!
Airnorth (standard livery) - would also love their E120 and E170 sister ships if also available!
Alliance Airlines (standard livery)
National Jet Express (with NJE on tail)
National Jet Express (with Cobham tail)
National Jet Express (white tail)
National Jet Express (Amas Bolivia hybrid livery, with and without titles)
Also, a slightly tricky livery from the past but one that might be appreciated by us Aussies!
Virgin Blue (AFL special livery)
