Coast to coast with S-aircraft

I really appreciate all those new destinations and I hate to say this, but flying an ATR or other S-aircraft from IAD to LAX seems to be a bit unrealistic. Is it possible to change this in the long run to other airports that are closer. Maybe airports like CVG, PIT, RDU, CLT, MCI, MSP, DTW could be implemented in the future as they seem to be better destinations for our little birds. Thx.
