Don't delude yourself, introducing glass jets into a turbo prop operation is too hard, history is working against you.
Why is introducing a glass jet into a turbo prop operation hard? The Q400 is all glass, and has similar performance to a jet.
However I highly doubt SSA/EAA crew will fly the B717. We are having trouble crewing flights already and pilots are leaving to fly elsewhere.
Unless they a) pay us a lot more to stay on the prop or b) give us jets and jet pay, people will just continue to leave.
Qantas might have ordered the c series already and keeping it tight lipped for commercial benefits. Looking at their order books, there are a few undisclosed orders and press releases. There are hints here and there that matches the characteristic of Qantas as one of the undisclosed purchasers.
