Stepping up into the biggest end of commercial aviation is a big, big ask.
There are already a number of aircraft manufacturers playing in the next tier - Bombardier (Dash 8), Embraer (EMB 120), Fokker (F50) and others. I can't really see them ever building something the size of a 787 or A380, but I concede it could be possible.
Looking at existing manufacturers, I think Antonov may stand a chance. They already have the AN-124 and AN-225, which might be engineered into passenger configuration.
With regards to new players, I was reading an article about the Indian company Mahindra yesterday[1]. They have ambitious aerospace plans, already some exposure to the sector through their purchase of GippsAero[2], obviously with much smaller aircraft, but also are located in a fast growing market. The article mentions Boeing's expectation of over 1,000 new commercial airliners needed in India by 2020. Maybe this is your new lean, hungry company.
Bombardier also build CRJs, business jets (Globals, Challengers and Learjets), does government work and builds fire-fighting aircraft. Oh, and the C-Series is a brand new a/c entering into the lower end of the Boeing market.
That being said, building even these small aircraft is a multi-billion dollar investment. If people here think that software design is hard. It takes a monumental amount of work to design a commercial aircraft and the manufacturing processes around it. Oh, and then there is the test phase. That part is fun.
