Perhaps EXT or CWL CDG as well. BHX to STR/LYS/TXL/HAJ/BER, not sure if BHX to NOC has been taken up yet either. Then EDI/GLA to EMA used to do reasonably well, but to do that they would need a base in either of the Scottish airports or EMA, and I just can't see the latter happening unless they believe EMA/CDG is worth a shot again. I'm sure that as part of the purchase they bought the detailed analysis of what worked and what didn't under the old regime and if they try to start what were financial holes again they'll go down the same pan as Flybe Mk.1.
There are niches but it will have to be slow and steady on a "big bang" approach as I really doubt the owners pockets are going to be deep enough to support too many new or restarted routes in one hit.
