Could this be an opportunity for BMI Regional to grow, replace the ageing E135's & 145's and up their operation a gear? They have been rumoured to be interested in bigger aircraft for some time. The 175's could be deployed on European routes, Dash8's on shorter routes making some of their shorter routes more economical, then cherry pick the current BE routes that actually make money and continue them as they are. They could also do with the crews as well!
From a regional flying perspective there certainly needs to be some streamlining, with BA Cityflyer, Cityjet, Stobart, BMI Regional, Loganair and Eastern Airways, and on a smaller scale Blue Islands and Aurigny
