Hopefully along with Berlin, flybe will crunch some numbers and maybe find an aircraft from an increasing busy fleet
I would say that is increasingly likely. As I suggested a few postings ago, they could hold on to an additional E195 for the winter and use a freed up E175 for daily service BHX-Berlin (SXF, or TXL if they can get decent slots) and BHX-ARN.
Alternatively, with their interests in Scandinavia, BMI Regional could be a candidate for the ARN service - though my personal preference for longevity and commitment to the route would be Flybe.
