Why not? With new regulations more and more aicrafts are getting obsolete, due to performance, to consumption and emissions etc.. without mentioning the number of machines continuously left on ground because of difficulty to find spare parts.
I believe an independent manufacturer competing with the A318/319 and B737 could only be beneficial to lower airline costs and let's not forget of the amazing Chinese area where more and more companies are rising up every day...
Why not?: 737-MAX7, A319neo, E-190, E-195, CS100, CS300, MRJ90, SS100 Superjet, AN158, ARJ21 - methinks that this market is a bit overcrowded already and with manufacturers / governments with much deeper pockets than Rekkof I'm sad to say.
