Be careful what you wish for
Flybe muscled into the market in the Southwest promising the earth and ultimately putting the local airline out of business. Once they had the monopoly they kept one route only which was the only one worth their while running on a 78 seater.
Flybe is about profit so forget any ideas about marginal routes to support local communities.
As for KOI and LSI, I doubt you would get anywhere near a full load out of either on a Q400 especially on a wet runway.
